Three Discworld computer games exist.
Discworld 1
A fiendishly difficult DOS-based click-and-point puzzle game, loosely based around the time/events of Guards, Guards, but this time with Rincewind in the star role.
Voice actors include Eric Idle (of Monty Python fame) as Rincewind, and Tony mumblemumble (Baldrick of Blackadder) as three quarters of the other characters in the game.
Discworld 2
A fairly trivial Win9x point-and-click puzzle game.
Discworld Noir
A semi-3d point-and-click detective store. Based on an original story rather than mashups like the first two.
