Pac-Man is rightly heralded as a classic, not just the best-selling arcade game of all time at over 100,000 units (even more when you consider every Ms. Pac-Man arcade machine has the elements of a Pac-Man machine inside it), but it’s solidly well-designed. All of its elements come together to produce a solid test of skill and strategy.

It’s not perfect though. The game possesses two major flaws that, in retrospect, made it a little less interesting to play now. The ghosts behave deterministically when they’re not vulnerable, meaning that patterns work against them and turning the game into a test of memorization and execution. And, every level’s maze is the same, which gets kind of monotonous. Tellingly, while Pac-Man was extremely popular for its time, its GCC-made follow-up Ms. Pac-Man had a much longer life in arcades, and it addressed both of these issues with the first game: ghost movement at the beginning of boards is randomized, and it had four mazes, instead of the original’s one.

Random Pac is a fan game, available on itch.io and made by Luca Carminati, that also solves the issues, and a bit more simply: it randomizes the maze for each level. This one change makes the game immune to memorization, and makes each level a kind of situational puzzle, as the player must use the maze layout as best they can to avoid being caught.

It’s not the only change made, but the others are, for the most part, in line with that one. Since the game is much less likely to extend endlessly, extra lives are awarded multiple times, first at 10K then every 50K points, instead of the once, by default, of the original. There are bonus levels in place of the intermissions that can be worth a considerable number of points.

The fruit bonus items that showed up twice during each level of the original game may now appear up to four times per level, which can be worth the majority of the player’s score if they can get up to the 5,000-point Key boards. Getting all four Keys is 20,000 points, which is two-fifths the way to an extra life by itself.

The game increases in difficulty a bit more slowly than classic Pac-Man. I’ve been to the 7th Key level; in the original, on the the 5th Key board, and from the 7th Key on, ghosts no longer become vulnerable when eating an Energizer (a.k.a., a power pill). Vulnerable times kept decreasing in my 7th Key game, but hadn’t cut out completely yet.

Another difference, and I’ll be going into some deep Pac-Man internals here. In classic Pac-Man, ghosts have three states, Scatter, Chase and Vulnerable. If Pac-Man doesn’t eat an Energizer, ghosts periodically enter Scatter state for a few seconds, then change back to Chase. You can tell when ghosts change between these states because they all reverse direction.

In most boards there are two Scatter periods, and the timers, both for entering Chase and Scatter, freeze while an Energizer is active on any ghost. In Random Pac, the timers don’t freeze; Chase and Scatter periods continue even when the ghosts are vulnerable. This makes Energizer timing very useful for decreasing the amount of danger you face: a short way into a Chase period, eat an Energizer and disrupt their pursuit! By the time they catch back up to you after it wears off they may be time for them to Scatter!

Ghost AI seems to be mostly the same, although unlike classic Pac-Man, each ghost doesn’t seem to have a set “home” location. They don’t intend to chase Pac-Man during Scatter, but instead fixate elsewhere on the board. The Orange Ghost’s Chase AI also makes use of its home location, making its behavior much less predictable, although it’s still easily the least threatening ghost.

Random Pac was Luca Carminati‘s first classic game remake. Since then, they’ve made many others, including Tutankham Returns, which we’ve linked to before. They’re terrific!

The other talks presented this year use music generated by this system for bumper and intermission ambiance. It really became the distinctive sound for this year’s conference.

There were plenty of other interesting talks this year! You can see them all at Roguelike Celebration’s YouTube channel. Here are 2022’s talks all in one playlist. And if you wish to attend next year, be sure to watch their homepage and follow them on Twitter (I have heard no word yet on other media accounts).

Today is the launch date of Unexplored 2! (Steam) The sequel to one of the more interesting roguelites of recent years, the original simulated a game world with a lot of depth, and played a lot like a real-time version of a classic roguelike with updated graphics.

I did a Q&A with the makers over on Game Developer a couple of months ago! (I can’t seem to find it right now, though….) They also have a dev blog over there if you’re interested in its creation!

So. Um. Have a trailer!

Short VGM Generator is on itch.io, and works by taking a pre-existing piece of music and attempting to make another piece of a similar style.

The Good Old Game Sound Generator is on GitHub, but for playing around you might be more interested in its Demo page. It takes a bit more effort to make something with it, but it’s a much more flexible tool. I must leave you to your own devices to make something of value, or at least of interest, using it.

The process that let him to create these tools is up on a page he made on dev.to. If you’re interested in generative music you should take a look!

I’ve known and spoken with Keith Burgun for over a decade now, and his early hit 100 Rogues for iOS was featured back on @Play. (It’s sadly now unplayable because of a combination of rights issues and Apple’s upgrade policy that makes old iOS software impossible to use.)

Many of Keith’s games made heavy use of randomization. 100 Rogues was a roguelike, Auro was a single-character puzzle/tactics game with randomized maps, and his current Gem Wizards Tactics (Steam, Switch, Xbox, Android) uses random maps.

But Keith is always reexamining his ideas. A while back he decided he didn’t want to keep making roguelikes, taking the ideas from it he liked and leaving the rest behind. And now he’s questioning his use of randomization as well.

He’s written an essay on his blog, titled “Space Narratives: A Map Randomizer Denounces Map Randomization.” It’s got some very interesting points, and he draws in the awesome Ocarina of Time Randomizer project in his discussion, as a way to have benefits of randomness without having to randomize the map itself. It’s good food for thought for developers interested in procedural content!
