The video I’d like to point out today is this one on the dungeon generation in the first Pokémon Mystery Dungeon game (19 minutes), which basically lays bare the entire scheme by which nearly all Mystery Dungeons construct their procedural death labyrinths.

I’ve played quite a few Mystery Dungeon games, including nearly all of the many versions of Shiren the Wanderer (Rainbow Labyrinth is the only one I’m missing), and these dungeon level types keep coming up again and again. I’d be very surprised if essentially the same code, or close to it, wasn’t used in all of them. The beginning of the dungeon generation explainer is at 5:03.

One interesting thing is that the dungeons generated by the various routines often create maps that can be seen as variations upon the dungeons from the original roguelike, Rogue itself. Rogue used a distinctive 3×3 grid of rooms. Sometimes a “room” might be a winding corridor, a dead-end or a dark maze, but it doesn’t take much playing to see the patterns used, and the Mystery Dungeon games obviously use a similar system for most of its floors, using differently-sized grids. Sometimes extra dead-ends are generated, and there are a few extra styles, but in its overall plan it’s Rogue-standard. It’s what the video calls the “standard generator.”

This isn’t all that the video explains, for just one example it goes over the details of how the game’s random number generators work, and also how they can be abused (the dungeon RNG is seeded to 1 at boot, which can be used to ensure dungeons generate the same way). I think it’s essential viewing for any Mystery Dungeon enthusiast.

For most of the episode we try to treat the game as if all that skeevy stuff doesn’t exist, but don’t close it when it seems like it’s over….

As for the skeeve, the game’s official website has a section marked OPPAI, which I do not link to directly from here, in case it gets Set Side B on some kind of list.

I don’t make many @Play posts these days, and I’m sad that I have to drag out the tag for something like this. I am working on a lot of discussion about Caves of Qud (if I can link to Omega Labyrinth Life here I can certainly call out Qud), but the game is so blasted huge! Hopefully I can bring you something on that front soon.

This year it’s happening between Saturday and Sunday, October 25-26. That’s the day after tomorrow! There’s an unusually good roster this year, and I don’t just say that because I helped find speakers for it this year.

We’ve already had a preview event with a couple of great talks, including a real star, Jon Perry, who created two of the best games in UFO 50, Mini & Max and Party House. While I spent a lot of time with Mini & Max uncovering its many secrets, it’s but a small fraction of the time I’ve played Party House. (If you want to hear Jon Perry’s talk, from September, you can find it here, as well as Ezra Stanton’s talk on Synergy Networks in roguelikes, and Alexei Pepers’ Designing for System Suspense.)

I’ve already gushed voluminously about Party House here. Let’s move on to this year’s talk schedule. Times given here are Eastern/Pacific/GMT. (The later times in GMT are pushed into the following day.)

Saturday, October 25th

Sunday, October 26th

If some of these talks seem like they’re spaced closely together, some of them are “lightning talks,” very short. Those have their titles in italics in the above list.

If you follow indie gaming circles, there are a fair number of exciting speakers among the talks! Jeff Lait (homepage) has made twenty highly interesting roguelikes, many as 7DRLs. Nifflas of course is the creator of Within a Deep Forest, the Knytt games, Affordable Space Adventures and others. Dan DiIorio is the creator of the oft-mentioned (at least in my hearing) Luck be a Landlord, and Zeno Rogue makes the long-lived, and brain-bending, HyperRogue.

And make sure to have a look at the Redbubble and Steam links too! In this year’s Steam selection, MidBoss and Shattered Pixel Dungeon are already on sale.

(EDIT: I had the Eastern times too late by an hour. The event will begin at 6 PM Eastern time.)

Tonight’s show is being done for free, but you still need a (costless) ticket for it, which you can get here. As has been usual the past few events, there will be a live MUD-like chatroom to participate in during the show, for interacting with other audience members, for submitting questions to the queue, and just for bumping around and exploring. The doors open a little before the talks begin, to let people get used to the space, and as a buffer against lateness.

I hope you can make it! Tonight’s talks are:

3:15 PM Pacific / 6:15 PM Eastern / 10:15 PM GMT / 12:15 AM CEST – 45 minutes

Fireside chat with Jon Perry: Host Alexei Pepers and Jon Perry will chat about game design and his contributions to UFO 50 such as Planet Zoldath, Party House, and Mini & Max! (Personal note: this is not one to miss. I have been obsessed with Party House, enough to write a gigantic strategy guide for it.)

4 PM Pacific / 7 PM Eastern / 11 PM GMT / 1 AM CEST – 30 minutes

Building Synergy Networks for better Roguelike Deckbuilders, with Ezra Szanton: Roguelike Deckbuilders live or die on the quality of the drafting decisions they present. When a player chooses between 3 cards, what is going through their head? This talk is about how to achieve deep but accessible drafting decisions which result in memorable games that excite players. Synergy Networks are a helpful lens for creating sets of cards that achieve these aims. Modeling the synergies between cards as a network allows us to use ideas from network theory like path length, density and hubs. Digressions will include characteristics of synergies, broad types of synergies useful for brainstorming, and why anti-synergy is just as important as synergy itself. This talk is informed by my work designing Hellscaper and Mr Magpie’s Harmless Card Game, two roguelike deckbuilders.

4:30 PM Pacific / 7:30 PM Eastern / 11:30 PM GMT / 1:30 AM CEST – 45 minutes

Designing for System Suspense, with Alexei Pepers: The host will give a talk which she gave at GCD and had previously been trapped inside the GDC Vault.

We love it when we find weird and unique indie games to tell you all about! Our alien friends to the left herald these occasions.

Writing about Nintendo fangames is fraught. Not that something might happen to me, the insidious grasp of their legal team doesn’t stretch that far yet, but for the games being written about. Remember AM2R, a fan remake of Metroid II that many believe was superior to Nintendo’s own revision? Then some big sites mentioned it, Nintendo heard about it, and they sent the creator a nastygram demanding they take it down. Set aside the fact that the game can still be readily obtained from numerous other sources; it still dumped a big bucket of freezing cold water on the hard work of its maker, which is hardly a way to treat fans, especially since the company’s prosperity depends on their good will. Nintendo must be really certain those enthusiasts won’t reject them.

About our own blog, I don’t think anyone at Nintendo personally reads Set Side B. I’m sure their well-paid legal staff has plenty better things to do than read an obscure little daily retro/niche/indie blog, even if it’s one that posts articles on their products really often. But it does seem possible that someone at Nintendo might run a spider, an automated program that scans the internet for derivative works related to their products.

Not romhacks, mind you. For some reason Nintendo doesn’t take a lot of interest in romhacks of their work in most cases. But fanwork that uses their IP in one way or other has been known to attract the attention of the legal Warios. That is why AM2R got stomped upon by the Kuribo’s Shoe of Civil Law, and it’s why Zelda Online had to retitle to Graal Online (a project that continues to this day under that name).

I tell you this so you’ll know why I don’t give the full name of the project I’m going to refer solely by the second half of its title: Dungeons of Infinity. Any person looking at the screenshots will be able to easily tell what game it’s referring to, and uses assets from, but web crawlers won’t, or at least I won’t make it any easier for them than the Youtube videos that contain footage of its play. If you figure you want to try it, which I hope you will, if you search for it you’ll probably find it. I’ll help you out by telling you it’s not the board game Dungeons of Infinity, which had a Kickstarter in 2024. Many of the top hits for that phrase will be about that, but not all of them. I trust you’ll be able to tell them apart.

Most of the things I like about (mumble mumble): Dungeons of Infinity are not related to the game from which it borrows. If they could find some helpful people to make similar graphics in the same style, and changed the name, they might be able to escape danger entirely, but that might require time and effort the creator doesn’t have. Whatever be its trappings, it’s a pretty cool random dungeon exploration game in its own right. It has a pretty active Discord. Its creator mentions there that they’ve recently lost interest in working on the game so its current version, 1.2.1, will probably be its last. It’s still pretty cool as it stands.

So the idea is, like in the other games in the series of, um, The Saga of Fitzgerald’s Wife, is to pilot a green-suited elf kid through dangerous and tricky dungeons and caverns full of monsters and traps, collecting items and uncovering secrets. What’s different is that the game is much more linear than those other games (much like the Four Swords Adventures titles), and the rooms and their arrangements are randomly determined. So… also like the Four Swords Adventures games, although this one is purely for solo play.

If you explore throughly enough you’ll always find a way forward, the game isn’t designed to give you unsolvable situations. But what can change, and quite a lot at that, is the items that you find. Weapons like the Bow, the Hookshot or the Boomerang have to be found, or sometimes bought, if you want to use them. None of these items are required to win, but without certain items, like Sword and Tunic upgrades, or extra Heart Containers, you’ll find the going much more difficult.

In fact, probably the game’s biggest drawback is that it falls prey, a bit, to fangame difficuly malaise. Bosses that in the original game aren’t hugely difficult here are tenacious damage sponges. Everything in the game has been tuned to be that little bit more difficult: you have less health, sources of healing are less common, and enemies take more damage. Due to the nature of difficulty, all of these individual sources of peril multiply together and become much harder than the sum of its parts. And (mumble mumble): Dungeons of Infinity is a permadeath game: if you take too much damage and run out of hearts, the adventure ends, so to keep going you have to start over from the beginning, fighting all the early enemies once again, and building a whole new collection of random items. If you’re not up for a challenge, well, you probably shouldn’t bother downloading it.

Here’s some details that it might be useful to know:

• You have a very limited inventory space. You can only hold five items by default. The bow & its arrows count as separate items too, as do your bombs and any healing items you find. You can find, or (more likely) buy inventory expansions, and there are items that help keep other items from taking up inventory spaces, but you’ll frequently have to make difficult choices for what to keep.
• On the other hand, items you drop, or don’t have room to collect, don’t disappear. They’ll remain on the ground in the room they were dropped or found in until you come back for them, or else take the downstairs (you don’t get to backtrack to previous floors). If you hold off on collecting hearts when you’re at full health, then when you do take damage, you can come back to pick them up later.
• Aiding in this, enemies that you defeat never return. It’s possible to clear whole dungeon floors of monsters, making them much safer to explore.
• In the bottom-right corner of the HUD, there’s a vertical map of all the dungeon levels, which gives you the low-down on where the bosses are. It also marks the location of save points. In the true spirit of permadeath these points are only for taking breaks, not for continually restoring from, but seeing as how the game is fairly long it’s good to take advantage of them, and refresh the mental batteries for a bit before tackling the next leg of the quest.
• It’s a shame that it’s pretty far into the game, but in the rebel village area on the 6th floor there’s an arcade with a pretty decent remake of arcade classic Berzerk in it, as well as an endless runner version of Pitfall with a recreation of the music from Pitfall II: Lost Caverns! If you get a few rooms into the Berzerk remake, you’ll find another mini-game, within that mini-game. I don’t know how deep this recursive ouroboros of gaming goes, but it’s a very nice touch.

While RC got its start as an in-person conference, when the pandemic hit they switched over to being entirely virtual, presented through video feed. All of their talks end up posted online, so anyone can see them for years after. But if you can attend during the conference you can participate in chat, ask questions of the speakers, and explore a very clever MUD-like chat interface!

I’ve tried to spread the word about Roguelike Celebration where I can, through social media and this very blog here. Every year they have several very interesting talks that, if you read Set Side B, I know you’d be interested in seeing. They’ve hosted Tarn Adams, co-creator of Dwarf Fortress, the creators of the original Rogue, and many other thoughtful speakers.

This year Roguelike Celebration takes place October 25-26. They sell tickets, but they also let people who are strapped for cash apply for a free ticket. (If you can pay for admission though, please do, as it takes money to run an event like this.)

And if you have a roguelike, or even vaguely-related project, please please please answer their Call For Proposals, to apply to present your work to their devoted audience of extremely thoughtful attendees! The CFP site is here, and their deadline has been extended to July 20th, so you have about three weeks to get in your proposal!

Give it a shot, it’s a great way to spread the word about roguelike work, or about a procedurally-generated game you’re interested in, or just something you think the world should know about.

By volume most game players, let’s be frank, are interested in the big AAA productions. But there are lots of people out there who are willing to give indies a chance, which roguelike games often are, and we have to stick together. Not only to talk with each other and build those connections, but to do it in public, non-corporate venues. Reddit largely is a sham these days, more interested in monetizing their userbase, and Discord isn’t web-searchable, and requires navigating a maze of requests that you upgrade to “Nitro.”

I do not lie: little volunteer-run organizations like Roguelike Celebration are a lot closer to the true spirit of the internet, and the World Wide Web, than those are. So please keep them in your thoughts, if you can buy a ticket, and if you have something to present, answer their CFP! You won’t regret any of those things.

It got by me this year, but the now 20-year-old 7 Day Roguelike Challenge, a gamejam where people try to construct a complete roguelike within a week’s time, finished up Saturday.

Not only has it been around a long time, but a number of games have come out of it that went on to greater things. Jupiter Hell got its start as a 7DRL project called DoomRL. The amazing Jeff Lait has made a ton of 7DRLs, and many of them have some awesome twist, like a game where you can make portals, but where the portals result in the world through them being rotated and possibly allowing you to get mixed up!

There’s regular several very interesting games in the challenge each year! Its itch.io page is here. This year’s theme was, simply, “roguelike,” and 819 people have joined it so far! I can’t wait to see what they’ve made!

He wrote a spoiler for Nethack called To Die: 50 Ways to Leave Your Game, which was a cataloging of ways to die in that game. This used to be available in several locations on the World Wide Web, but now I can only find it in one place. To help preserve it for later generations, I paste it below in full.

I feel that first I should say a word about how Nethack pages have become scarce lately. The old Steelypips spoiler site is still active, but many of the other sites it links to have perished. (Some of them have academic URLs, and have probably fallen victim to the declining web investment of universities. To think in my lifetime I’ve seen the rise and subsequent abandonment of the internet as a tool of knowledge. I blame social media!)

I should see about preserving old spoiler documents on the living internet, but until I get something put together, here is Boudewijn Wayers’ list of ways to die in Nethack.

Multiple long ages of the internet ago, famed nethacker Boudewijn Wayers wrote a spoiler called To Die: 50 Ways to Leave Your Game. It was published on his long-gone Nethack Home Page, but copies of it remain scattered around the internet, although currently I can only find one copy on Google, from a page on tecfa.unige.ch. I’m quite sad that this venerable piece of hack lore is in danger of extinction, at least to people who don’t know the magic codes to enter on the Wayback Machine.

To Die is a wonderful bit of roguelike lore, so great that I’m posting it in full here soon to help preserve it. But today’s focus is on a more recent variation of it: a Youtube video from TheZZAZZGlitch listing every way to die in Pokemon Mystery Dungeon Blue and Red Rescue Team. (21 minutes)

In the spirit of the communal spoiler files of old, I enter the list of death causes here, in easy-to-search-for text. For the details, I refer you to the video. Note that every source of damage in the game that has the potential to reduce the player’s HP to zero has a corresponding entry in this list, so it serves as a map to every cause of harm in the game’s Pokeverse.

WAYS TO KICK THE POKEBUCKET (33 possible causes)

was defeated by (attacker)’s (move) (this is the most common cause of adventure ending)
missed a Jump Kick and wiped out.
missed a Hi Jump Kick and wiped out.
fainted from the foe’s Destiny Bond. (an instadeath)
fainted, covered in sludge.
fainted from a move’s recoil damage.
fainted from damage it took bouncing.
was defeated by a foe’s pent-up energy.
fainted from stepping on spikes.
fainted from a bad burn.
fainted, unable to bear constriction.
fainted after the poison spread.
fainted while still being wrapped.
was felled by a curse.
was drained to nothing by Leech Seed.
fainted from hearing Perish Song. (another instadeath)
fainted while in a nightmare.
was felled by a thrown rock.
fainted from hunger.
disappeared in an explosion.
tripped a Chestnut Trap and fainted.
fell into a Pitfall Trap and fainted.
was defeated by a Blast Seed’s damage.
was transformed into an item. (instadeath)
fainted from being knocked flying.
was felled by a Pokemon sent flying.
gave up the exploration. (quitting the game, not explicitly a death, but serves the same purpose)
was blown out by an unseen force. (spent too long on a single floor and was expelled by the Winds of Kron)
returned with the fallen partner. (your sidekick fainted, so you left too, automatically)
fainted due to the weather.
failed to protect the client Pokemon. (FISSION MAILED)
fainted from a Wonder Orb.
fainted from an item.

Unattainable but still used in the code, waiting for a moment that can never come (7 causes):

was transformed into a friend. (what?)
left without being befriended. (hwat?)
was defeated by debug damage. (nooo not debug damage)
was felled by a thrown item.
was deleted for the sake of an event. (oh okay then)
went away. (so long)
was possessed. (spooky)

Three messages exist in the code but with no way to activate them, even theoretically:

fainted from a debug attack.
was defeated by a powerful move.
fainted due to a trap’s damage.

It’s on the most recent Shiren the Wanderer game, The Mystery Dungeon of Serpentcoil Island, a.k.a. Shiren 6, and I hope I’m not spoiling things when I say it’s really fun. The episode is an hour and a half, we had a great time recording it, and here it is!

Roguelike Radio #159: Shiren 6, with Rob Parker and John Harris (1h29m)

rodneylives

In terms of depth, this post is rated 4 out of 5: highly detailed information for obsessed fans and game designers.

The first (28m):

And, the second (44m), it goes further into the weeds and is longer:

So, here’s a tl;dw overview of the first video. Despite the length, this is really only a brief summary! Some Body got their information by reverse engineering the games’ code, so it should be considered authoritative.

PMD has three times of actions, moving, attacking and using items. First they try to use an item–if there is no item to use, or the situation isn’t appropriate, or there’s a random component and they choose not to, they fall through to attacking. If there’s no one appropriate to attack, they fall through to moving or wandering. If they’re not pursuing a target and aren’t wandering, they wait in place.

Awake Pokemon try to reach a target: team members try to reach the leader (you)*, enemies try to reach a party member of yours. If they are following someone, they try to reach the target by default moving diagonally before moving orthogonally. This is good to know, and an effective strategy, since it’s harder to escape a cardinal-adjacent Pokemon than a diagonal-adjacent one. If a Pokemon has a target in sight but can’t move towards towards it, it doesn’t move.

(* Note: for teammates, this assumes the “Let’s Go Together” tactic is in effect. Generally, tactics settings are covered in the second video.)

No Pokemon can move towards a target they can’t see. Sight in Blue & Red Rescue Team is two spaces around them, or throughout a lit room they are in plus one space into corridors. Of course, invisible targets can’t be seen, even if they’re nearby. Note, a quirk of the Mystery Dungeon series generally: when standing in the first space of a corridor, you can only see slightly into the room, but everyone in the room can see you. While your default sight range in darkness is two spaces in the PMD1 games, instead of MD’s standard 1 space, you’re still a bit blind when moving into rooms. Notably, that two space distance around you is a square, so in corridors with bends in them you get a bit extra sight distance.

Now comes the interesting part (to people who are as obsessed with roguelikes as I am): what happens if a Pokemon loses sight of its target? In PMD1, it considers the last four locations the Pokemon was in, and tries to go to the one it was visible in most recently. Note in bent corridors, it becomes harder for a character to lose its target.

If the target is four turns outside of the follower’s sight, it has lost track of it, and the follower begins wandering randomly. This can happen if the Pokemon has never had a target (none has come into sight), or the target or follower teleports, the target moves over terrain the follower cannot cross, or the target moves away when the follower is occupied, or, due to the variety of events that can happen in the Mystery Dungeons, other ways.

Followers without targets wander randomly. When they spot a target, they cease moving randomly and pursue it. But if still wandering, in rooms, they pick a random exit, go to it and go down the corridor. In a corridor, they follow it until they reach a room (then entering it), or they reach an intersection. At an intersection, we see an interesting behavior: PMD1 occured before Chunsoft switched over to making wanderering monsters pick random directions at corridor intersections! In later Mystery Dungeon games, including later Pokemon Mystery Dungeons, wandering monsters go straight in intersections if they can. This is behavior that can be relied upon, but not in PMD1.

Outmatched Pokemon can decide to flee, essentially, moving away from their targets instead of towards. In rooms, they pick the exit furthermost from their pursuer, unless they moves them towards that pursuer; then they just try to get away as best they can, likely remaining in the room. A quirk of this: sometimes a fleeing monster breaks for an an exit that is more distant from the target, but not away from at attacker, giving it a free hit. The circumstances around this are complicated: the explanation begins at 7:16 in the first video.

For attacking, Pokemon have up to four moves, and a normal “attack.” This generic attack is not part of the main Pokemon game series. It was present in the first two PMD games, but after that became less effective. In the fourth and fifth PMD games, the normal attack only does five points of damage, and in the Switch remake of Rescue Team, it does no damage at all; it’s only a tool for passing time. But we’re still in the realm of PMD1, where “normal attacks” are not only useful but frequently used, because they don’t consume any PP.

Attacks are chosen based on a weighted average of all the usable moves. Each move has its own weight value; the normal attack weight’s varies according to the number of other moves available.

Ranged attacks are an interesting case. If a Pokemon has a ranged attack, and an enemy that can be attacked at a distance, it triggers the attack routine, where it picks a move from those available, but then only actually performs the move if the attack can reach its target. This can result in an attacker passing up opportunities to attack while an opponent approaches it. Out of fairness, room-range attack moves are only used by the AI when adjacent to an enemy.

Items have a bunch of minutiae associated with their use by the AI, but a lot of it is pretty ordinary. A few highlights: teammates can throw held negative status equipment at enemies, wild Pokemon start using items at Level 16, and there is only one Orb that wild Pokemon can use, and teammates can’t use it: the Rollcall Orb, for them, summons a number of other wild Pokemon into adjacency with them.

Honestly, the roguelike scene is so large now that no one person could reasonably be expected to keep track of all of it. But there is no need to; others hold aloft that particular torch. Here’s a couple of videos, then, on getting started in Caves of Qud.

Publisher Kitfox Games (who also publish the Steam release of Dwarf Fortress) sponsored a video with “Getting Started” right in its title. Here it is (18 minutes):

It contains information on the different modes, the best starting location for beginners (Joppa), basic controls, navigating around the starting town, how to get around the world map (reminiscent of Alphaman!), how to spend kill points, how to read things, how to examine Artifacts, how to experiment with things (even if it gets you killed sometimes), how to steal things, performing the water ritual, and some combat tips.

Another, slightly longer at 24 minutes, intro video is by Rogue Rat:

It covers ranged weapons, the town of Joppa, Truekin, what to do when you get lost, some different skills to learn, gaining levels from giving books to a specific NPC, using its Crawl-type Autoexplore feature and other topics. Rogue Rat did a longer, more basic, intro video (34m) last year that went over many of the same topics as the first video here.

Here’s an embed, but note that WordPress doesn’t seem to accept the link for embedding with the time code linking directly to my talk, so you’ll have to skip ahead yourself to 6:10:18 to get to it. Or you could watch some of the other very interesting talks on the way there! Either way!

It’s being held entirely online again this year, and offers a fun social space to explore that’s kind of like a MUD! Roguelike Celebration’s schedule is here, and you can get tickets for $30 for the whole event here. They usually set aside some free tickets for people who can’t afford the fee, although you might have to check around to find them.

Roguelike Celebration is nominally about roguelikes and procedural generation, but I think it’s interesting from a wide variety of gaming perspectives, and every year I find several talks that are incredibly interesting. Past years have offered presentations from people who worked on games as diverse as Kingdom of Loathing and Blaseball. Here are the talks being offered this year:

Saturday

• Harry Solomons: Trampling on Ghosts: Hauntology and Permadeath
• Cezar Capacle: Enhancing Narrative Through Randomness and Complications
• Max Bottega: Keeping Art Direction interesting in a procedurally generated world

They keep using terms from Chunsoft’s Mystery Dungeon games, especially Torneko no Daibouken from the Super Famicom, but seem to have a good sense of how those items connect to and were inspired by Rogue.

They also die a lot. Because Rogue doesn’t want you to win. It was made for a community of players who would play it over and over, and were competing on shared scoreboards on university machines, and indefinite play makes for a poor measure of player skill. Standing and trading blows with every monster is a bad strategy in Rogue in the long run. Instead, it helps to run from strong enemies, to build up more hit points so as to defeat them, and sometimes in order to escape them to the next floor. Rogue’s monsters grow in strength as you descend fairly quickly, and the player is usually not far ahead of them in the power curve. Then around the time Trolls show up they’re roughly an even match, and they keep getting tougher. The point where the monsters become stronger than the player is different every game, and depends a lot on which items the player has found and has identified, but it always comes eventually. They eventually get pretty far, dying on their fifth attempt to a Griffin on Level 18.

‘@Play‘ is a frequently-appearing column which discusses the history, present, and future of the roguelike dungeon exploring genre.

Gary Gygax was a weird person. I won’t get into his life or history or, the casual misogyny of AD&D character creation, or the Random Harlot Table. But he did know a lot about medieval weaponry and armor, and to some degree this obsessive interest seeped out and infected a whole generation of nerds.

I know which is generally better: leather armor, studded leather armor, ring mail, chain mail, splint mail, plate mail or plate armor. I know that, although in life each is different, battles are random, and there’s countless factors that might determine who would win in a fight, the order in which I have given them is roughly how effective they are, because it’s the order that Armor Class increases, sorry decreases, in classic Dungeons & Dragons.

While the list of armors is presented, in practically every Player’s Handbook, with their effects on protection right there in order, unless you’re steeped in the material, it is not obvious, just from reading the names of the items, which is supposed to be better than another.

This is a considerable roadblock, and one I struggled with for a while, when I first tried to learn to play Rogue, because that game expects you to know how effective each piece of armor is. You start out with Ring Mail +1. You find a suit of Splint Mail. Should you switch? People who play nearly any classic roguelike are going to run against this eventually. Even now, some games just expect you to know the relative strengths of each.

If you decide to take the chance and try it on, to Rogue’s (and Nethack’s) credit, it tells you immediately how effective the armor is on the status line, and you can compare its value to your past item. To Rogue’s (and Nethack’s) detriment though, if the new armor is cursed, you’re stuck with it, until you can lift the curse (to a new player, unlikely) or die (very likely). And then, unless you’ve been taking notes, you’ll still probably forget the relationship between the two items, meaning you’ll have to guess their relative value again later, and deal with the same risk.

Classic D&D tended to give short shrift to the intricacies of real-life armor use, simplifying a complex topic beyond perhaps what was appropriate. AD&D attempted to remedy that by going overboard, giving each armor ratings according to its bulkiness, how much of the wearer’s body it covered, how much it weighed and how it restricted movement. Gygax’s tendency towards simulation is responsible for some of the most interesting parts of the game, but it didn’t help him here I think.

Most classic roguelikes, at least, use the “bag of Armor Class” approach to armor, which is probably for the best. Nethack probably goes to far in the Gygaxian direction. If you find Plate Mail in Nethack, you’re almost entirely better off just leaving it on the ground, even despite armor’s huge value, because it’s simply too heavy. Even if you can carry it without dipping into Burdened status, or, heaven help you, Stressed, its mass and bulk lowers the number of other items you can carry before you reach Stressed, and carrying many other items is of great importance. This is the secret reason that the various colors of Dragon Scale Mail are so powerful in Nethack: it’s not that they have the highest best AC in the game (though they do), it’s that they’re also really light! Even if you don’t get the color you want, it takes concern about the weight of armor completely off your list of worries.

The use of armor underwent revision throughout D&D’s development. (This page lists the changes in detail.) For reference, the relative quality of D&D, and thus roguelike, armor goes like this.

Why the difference in values? Up until the 3rd edition of D&D, Armor Class started at 10 and counted down as it improved. 3E updated a lot of the game’s math, and changed the combat formula so that AC was a bonus to the defender’s chance to be missed instead of a penalty to the attacker’s chance to strike. Because of that, now it starts at 10 and counts up. The changeover was a whole to-do, I assure you, but now two editions later we barely look back. Back in that day others were confused by the system too, and even Rogue used an ascending armor score. But Nethack, to this day, uses original D&D’s decreasing armor class system.

If you compare those values to those used in 5th Edition, you’ll notice that even the new-style numbers don’t match up completely. As I said, while the relative strengths have remained consistent, if not constant, the numbers continue to change slightly between versions.

That concludes this introductory level class. You’re dismissed! If you’re looking into the relative effects of different polearms… that’s the graduate-level seminar, down the hall.

Most Satellaview titles are extremely obscure now, with their only remaining remnants that aren’t languishing in a vault somewhere inside Nintendo (if they even exist there) being saved data files on aging flash memory cartridges in the possession of diehard Nintendo players and collectors in Japan. Satellaview was treated as a way of distributing disposable software, games and other programs that were tied to a specific date or time, so there are a good number of lost items for it, and many will probably never be recovered.

Entropy and bitrot are huge problems with computer software of all types, and it’s shocking how little most companies, even Nintendo themselves sometimes, seem to think about recording essential parts of their past. So any successful reclaiming of old data from the land of howling hungry ghosts is good.

That’s why I’m remarking here that Satellablog, dedicated to recovering and making playable as much old Satellaview software as they can, has managed to obtain a copy of Episode 3, of the Satellaview version of Shiren the Wanderer, “Save Surara” or “Save Surala” depending on the tastes of the person romanizing the title. That means episodes 2, 3 and 4 have been found, leaving only the first episode.

Save Surara was a Soundlink title, like the releases of BS Legend of Zelda. That means they were intended to be played at the same time as a special audio broadcast, and contained events that were timesynced with that broadcast. Without the broadcast (which are usually lost now), Soundlink games can’t be entirely played as originally intended, but it’s still better than nothing.

Here is video of Episode 3 in action. It’s about 49 minutes long. It’ll have to be modified to get it into a state where people who aren’t into romhacking will be able to play it themselves:

With three episodes recovered, there’s still hope that someone in Japan saved a copy of Episode 1 on a forgotten flashcart resting in a closet somewhere. Frog bless all of you awesome hardware horders over there!

There are a few bugs in Dungeon, now basically impossible to fix, that I’m trying to track down and document, and I’m also working on improving the documentation, as well as provide some useful goodies with the system, like a disk of monsters, equipment and magic items. That’s useful because Dungeon has a special feature where it’ll take the monsters and items on a “Data Disk,” and scatter them around a dungeon map of its own creation. It calls these randomized adventures “Lost Worlds.”

Lost Worlds operate as a kind of quasi-roguelike. The Dungeon software creates a random map and places random items around it, but once created it becomes a Dungeon adventure that any created character can explore as many times as they like. While it doesn’t have roguelike tactical combat gameplay or random item identification, it does have a form of permadeath. Characters only get three lives to advance their level as far as they can go.

Lost Worlds are interesting places to explore, but there are some bugs in them. It is possible, in fact pretty easy, to get stuck in a part of the dungeon from which one can’t escape. Sometimes a one-way door leads into an area that can’t be escaped, and sometimes a passage-blocking trap will strand the player’s character in a dead-end. And once in a while a Lost World is downright unfinishable, its goal item disconnected from the parts of the dungeon the player can even reach.

While there are spells (Passwall and Teleport) that can release a trapped character, if they aren’t available the character is not completely lost. If you turn off the C64 (or close the emulator), then return to the Guild screen, the character will be marked as GONE. Over time, measured in loads of the Guild menu, the character will eventually find their way back on their own. It takes quite a while for this to happen though: I counted 15 loads, saving the game each time, before a GONE character returned.

This video (23 minutes) is is something I recorded myself as a demonstration of both Dungeon’s gameplay, and its Lost World adventure generation. It uses a set of 30 low-level monsters and items based on the stats of the old Basic edition of D&D, and a set of magic items I created for usefulness and to show off Dungeon’s spell set.

So, why would someone want to play this game, when there’s so many other newer CRPGs out there to play?

• The idea of rolling up a character and taking them through scenarios made by other people, to try to get their level up as high as they can get before they die three times, is great. My hope, perhaps misplaced, is this release will inspire other people to make dungeons for others to play, and I look forward to seeing them myself.
• The magic system of Dungeon, while it doesn’t allow for characters to learn spells themselves, is unique in that most of the spells are utility spells! There are spells for passing through walls, for teleporting anywhere on the map, for revealing terrain, for seeing in darkness, for giving oneself a damage shield, for locating the goal item, for disarming traps, and more. There is only one direct damage attack spell! Spells are more like tools than something you use to pound through the enemies.
• The dungeon model allows for dark areas, traps that block exits, two-way and one-way teleporters, secret doors, one-way doors, and decorating dungeon maps with PETSCII graphics. The simplicity of the dungeons, all of them fitting on one screen, works in Dungeon’s favor. No dungeon can be too large since they must all fit within the bounds of the map grid.

There are unique design considerations for making Lost Worlds too. Even though the computer creates the maps unaided, since it populates them from the monsters, items and traps that are on the Data Disk, the difficulty of the resulting dungeon is affected. The various doodads are distributed without apparent heed for what they are; I wonder if the generator actually cares for their identities or if it just checks how many of each type are on the disk, so as not to exceed that number.

If there are more easy monsters, more powerful items, and more weak traps on the disk then the dungeon will be easier due to their corresponding numbers being greater, and vice versa. It occurs to me that one of the flaws in the dungeon generation I mentioned could be alleviated, by not giving it one of the wall creating traps that could trap a player in a dead-end, but that also makes the dungeon a bit less interesting, so I’ve left it in the mix I use.

I recognize that, if I let myself, this might become a Dungeon blog. Rest assured, I’m not going to take it that far. But I really hope that some people give Dungeon a chance. While sure it has its inspirations (one person on Mastodon said it reminds them of Phantasie, a somewhat less obscure early CRPG), I think it’s pretty unique, and deserves for more people to have a look at it. I’m particularly pleased how well the sample monsters and items I made work in the Lost World framework, and I’m trying to think of ways that it might be improved. More on this later… but, not immediately, I think.

Here is the title screen (which is a spoiler for after finishing the main dungeon, although that is really only a short way into the game):

After you finish every other task in the game, including finishing the final 99 Floor “megadungeon” where most items are unidentified, the title screen changes to add a nice rainbow:

I forgot to get a picture with the title in place. I can’t go back and get it now because of what followed….

There is one more thing to do at that point though. That is to play through the megadungeon again, but finding 12 “Celestial Stones” that severely restrict your inventory by the end.

Well, I’m not sure if they really counted on anyone doing that? There doesn’t seem to be much reward for it. It doesn’t go remarked upon by anyone in the game. But it does change one thing: the title screen. Here it is:

I like the red “IN SPACE” stamp! Sadly, all the graphics in the actual game still show an island floating in the atmosphere, and not in orbit. I wonder if they plan on doing something with this in an update? That seems like a lot of extra work for the benefit of not a lot of people.

Looking through my screenshots, I found this illustration that can be unlocked for behind the main menu, showing Shiren stumbling upon a Monster House:

There’s a lot more to say about Shiren 6, after I gather up my thoughts about it….

‘@Play‘ is a frequently-appearing column which discusses the history, present, and future of the roguelike dungeon exploring genre.

It’s the shortest @Play column ever!

What is happening here? This is the newest Mystery Dungeon game, Shiren the Wander: The Mystery Dungeon of Serpentcoil Island. It’s actually a great deal of fun, a sharply-designed entry in the long-running classic roguelike series.

This isn’t “roguelike” like half the games on Steam. This is a true roguelike, even if it doesn’t have ASCII graphics: a turn-based RPG with substantial randomized elements, that demands that you live (or not) by your tactics, strategy and wits. I don’t begrudge others appropriation of the term, but it does mean I have to now use the qualifier classic when I want to discuss the old style. Really, it’s better to call games not in the original style roguelite.

The dungeon depicted is Heart of Serpentcoil Island, the traditional end megadungeon that most Mystery Dungeon games have. After finishing the “main” dungeon, and playing a lot of extra bonus dungeons that each show off a specific element of the game’s engine, there’s the megadungeon: a 99-level gauntlet of terror where you enter at level 1. None of the items you’ve collected throughout the rest of the game will help you here. You must start from scratch with just a riceball. You don’t even have a weapon or a shield to begin with: everything you have, you must find along the way.

The game doesn’t pull many punches in this dungeon, as you can see. At experience level 1, every space in a room (other than the entrances: that’s a secret tip for you!) could contain a game-ending trap. The only consolation is that they’re really quite rare! I was exceptionally unlucky in this run.

Additionally, the uses of many of the items, the scrolls, grasses, pots, bracelets and incense found in the dungeon, are unknown: their effects must be discovered, through means both blatant and subtle, for yourself. Some of them will be essential to your survival, let alone success; others, like the Ill-fated Seed, you really want to avoid using.

It’s a ludicrous test of knowledge and skill, and a fitting capstone to the game. If the experience shown in the video seems like it might put you off, at least it shows conclusively that the game isn’t taking it easy on you. If you win, and it can be won, it’s a great accomplishment. I’m still working on this one myself; I’ll let you know how it goes.

I did this on my rarely-used Twitch channel. I’ve put the recordings of the play in a video collection, which you can see here.

I’m not going to say this means the game is easy. I can finish Super Famicom Shiren on one try too. I’ve been playing roguelikes for, oooh, over 30 years now? Shiren 6 falls a lot closer to the first Shiren games than Shiren 4 and 5, and I couldn’t be happier about that. I plan on written a full review later, after I’ve recovered from staying up all night playing this game.

I’m sorry that this isn’t more generally interesting, but I’m pretty jazzed!

I never finished my recap of 2023’s highest-ranked 7DRL entries, and 2024 is rolling around already, set to begin on March 1st! Here is it’s itch.io page, and Cogmind creator Kyzrati’s Mastodon mention.

7DRL, the 7-Day RogueLike challenge, is one of the oldest still-going gamejams out there, and still among the most interesting. Every year a number of surprisingly interesting games come out of it. One year, back when @Play was on GameSetWatch, I took it upon myself to look at every game that succeeded at the challenge that year. I think it was 2011? Even though it took weeks, enough time that I vowed I’d never review every game again, even some of the lesser ones had some interesting aspect to them.

This year will undoubtedly add yet more game to that backlog, hooray! That was a sarcastic hooray, I won’t deny it. But it was also, in a sense, an honest one too. More interesting and unique games mean more fun for everyone, fun that doesn’t cost $60 + DLC prices. And making them means more experienced gamedevs making things they like, things that don’t rely on multi-hundred dollar triple-A outlays of cash to realize, and that helps us, very slightly yet perceptibly, reclaim gaming culture from the wash of monotonous big-money content with which we’re all inundated.

It all starts March 2nd, so if you’re interested in participating, get ready to make! And it all ends, mostly, on March 11th, so get ready to play! (I say mostly because technically the challenge isn’t absolutely time-locked. But it’s a good period to aim for and build hype around.)

Nethack uses the system time-of-day clock to affect the game in modest ways. It figures out the phase of the moon, and if it’s a full moon the player’s “base luck,” the number at which it starts and tends to trend towards, is +1. Luck affects the game in many minor ways, most notably affecting the to-hit chances of striking monsters. Full moons also affect werecreatures and the chances to tame dogs, but those effects are highly situational.

Playing on a new moon has one effect, but it’s a big one. If you’re fighting a cockatrice and you hear its hissing, and are not carrying a lizard corpse, then you always begin turning to stone, instead of there only being a one-in-ten chance. This is what is called a “delayed instadeath”: you don’t die immediately, but if you don’t take immediate action it’ll happen in the next few turns. That’s the next few turns from the game’s perspective: various events may conspire to prevent you from getting that action at all. (The Nethack Wiki’s page on petrification is instructive.)

If you do get the turn, one of the things you can do is eat a lizard corpse, or that of another acidic monster. (Eating dead monsters raw is something you just end up doing often in Nethack.) If those aren’t at hand, what usually works is prayer, provided that you haven’t prayed too recently, your patron god is not angry with you and you’re not in Gehennom. Ordinarily, if you haven’t been playing badly, your god isn’t mad at you. If you’re in Gehennom you’re in the late game anyway, and probably have had ample opportunity to obtain one of the several ways of halting impending calcification.

Prayer is nearly a universal panacea, if it’s available. But there is one other thing that can block prayer: if your luck is negative. Even if it’s by just one point, prayer will never work.

That’s where the only other date effect in Nethack comes into play: on Friday the 13th, your luck defaults to -1, the opposite of the full moon effect. So, unless you’ve increased your luck by one of a number of means, prayer will never work on Friday the 13th. And today is both a new moon night and Friday the 13th. Other uses for prayer won’t work either: if you’re weak from hunger? Too bad. Low on hit points? Sorry. Punished with a ball and chain? Not going to work. Wearing cursed levitation boots? LOL.

Days that both have a new moon and are a Friday the 13th are rare. The last one was in July of 2018, before that November of 2015, and the one before that was in 1999. So, um, if you’ve been thinking about trying out this weird old roguelike game you’ve heard about, you might want to wait a bit. Until tomorrow, anyway.

Interestingly, the theme of this one is “back to basics,” suggesting that some of the greater mutations of the more recent games, like the Night rules, equipment experience and such, will be pared back. Some of those rules I like and some I don’t, but I have said that more recent Shiren games, while fun, feel like they’re lacking something. Some of the series enhancements starting from around Shiren 4 (which never got an official English release) I have issues with, particularly, monsters always going straight through blind intersections if they have no knowledge of Shiren’s location, allowing the player to take advantage of the AI to avoid conflict; and that Shiren’s healing rate actually decreases, not just relative to maximum HP but in absolute terms, as he gains experience levels. These are relatively minor qualms though, and most players won’t even notice them.

Here is that trailer:

Some noteworthy elements are the return of Shiren’s lady friend Asuka (who despite appearances is several years older than him), and of giant-sized boss battles, possibly using some of the engine enhancements done to facilitate large Pokemon in Rescue Team DX. I also appreciate that the story appears to be a naked grab for loot! It’s always felt to me that a wanderer’s life is, or should be, a hard-scrabble existence, and while our rogueish characters may affect the fate of the world, they’re still usually in it for themselves. That way, if they fail (and they fail often), you can laugh at them more than feel sorry for them.

I keep trying to do more @Play columns but other work continues to get in the way. I have a fair number of subjects to write about now though, not the least of which being my ill-advised decision to buy the super-skeevy Omega Labyrinth Life on Switch. I feel like paying money for that might have gotten my name on a list somewhere, so I might as well get some column inches out of it!

I’ve been thinking about doing more @Play lately, but in the meantime, please read this mostly nice, lengthy article from The Digital Antiquarian on Rogue and its legacy. I say mostly because there are a few minor points I disagree with. Maybe I’ve played too much of it, but experienced players tend to view vanilla Nethack as maybe a bit too easy. There’s a ton to learn, but once you’ve internalized it all, you come to realize that most situations have counters, and it comes down to knowing what they are, and not pushing your luck too far. Ah! I’ve not said much on Nethack for years now! I should get back to doing that….
