Zangband

The game of Zangband is a single player computer role playing game set in the world (although 'worlds' might perhaps be more accurate) of Amber created by the author Roger Zelazny. Zangband is a variant of the game Angband which is descended from the game Moria which is in turn based upon the game Rogue (hence Zangband's classification as a roguelike game). (zangband.org)
