The Dungeons of Moria (Moria) offers gamers a single-player, infinite dungeon simulation. Apart from name and final adversary (a Balrog), most Moria titles borrow lightly from the writings of J.R.R. Tolkien. Popular derivative games include Imoria and UNIX Moria (Umoria) and its descendants, Pmoria, Morgul, and kMoria. Generally, members of this game family are open source, and working versions exist for most computing platforms. The Pits of Angband (Angband), first branched from Moria, has grown over the years to become its own family of roguelikes. Information regarding Angband resides in the Games: Video Games: Roleplaying: Rogue-like: Angband.
