TotR identifies Moria as the first follow-up game to Rogue. My notes have it popping up three years after the original, which seems like an impossibly long time now for no one to have made a copy, but even Advanced Rogue, which was built off of Rogue code, didn’t see the world until 1984. Moria, by contrast was written from scratch. Moria’s Wikipedia page notes that Koeneke originally wrote it in a form of BASIC, but rewrote it in Pascal, and I think that’s probably the version that first saw distribution.

(A good place to look for the relative appearance times of roguelike games is this page on the Tangaria website. There is also BALROG, which no longer exists on the living web but is preserved on the Wayback Machine, although a link to it currently eludes me.)

Moria was converted to the C language to produce UMoria, which the credits to Blizzard’s Diablo cite as a direct inspiration. A prototype of Diablo was found some time back that was turn-based, and was even closer to the Moria play style. There’s also GMoria, another variant of UMoria.

A browser-playable version of Moria is reputed to reside here, but currently seems broken. Moria itself wasn’t ported beyond Pascal, but UMoria was written in C and so managed to proliferate. User polluks at GitHib has preserved and cleaned up the source to UMoria and released a version 5.7 that remains true to early versions, and runs on Windows, Linux and macOS. Previous versions ran on VMS, DOS and Amiga. Their account also maintains several other versions of Moria, including the Pascal source of the VMS version.

The object of Moria is to descend into the titular mines and defeat the Balrog that gave Gandalf so much trouble. Some of its many improvements over Rogue include a town level where players can purchase and sell items, more types of equipment including helmets and boots, the need to carry a light source in the dungeon, and levels that could be much larger than one screen in size.

Angband players will find most of this familiar; while it has a much longer dungeon, in structure its apple doesn’t fall far from Moria’s tree. Both Moria and Angband place the game emphasis more on fighting and tactics than Rogue.

Rogue was popular in the culture of university computing, but its source was closed, and what variants it got were built off of leaked code. Moria was the first open source roguelike, which allowed for its conversion to C. This C version was renamed to UMoria. UMoria is the ancestor of mighty Angband, which is one of the most-permuted games ever made, with well over 100 variants, with even more appearing once in a while.

I can’t resist turning this into a parable about the virtues of cooperation and sharing. Because of Rogue’s closed source, its immediate variants are very hard to find now, with only the versions preserved by the Roguelike Preservation Project surviving, and Rogue itself has largely been overshadowed by NetHack and its variants.

For more on UMoria, back in 2015 Roguelike Radio did an episode on it. There is also a good Moria resource page.
