Unangband is a variant of Angband that has a distinct flavor. You adventure in Tolkien's world, through towns and wilderness and multiple dungeons, journeying from Bree towards greater and greater danger. This variant roughly doubles the monster list, expands the class-based system of Angband with numerous possible specialties that let you fashion a unique character, offers an absurd variety of terrain, and includes a bunch of major interface improvements, including better presentation of graphics and an experimental isometric view.
Lycanobot is an IRC bot used to play the game, "The Werewolves of Thiercelieux" (Les Loups-Garous de Thiercelieux), which is quite like Mafia, the traditional Russian party game.
