Discworld Noir is a computer game based on Terry Pratchett's Discworld comic fantasy novels, and unlike the previous Discworld games is both an example and parody of the noir genre. The game was developed by Perfect Entertainment and published by GT Interactive. It was originally released in 1999 for Microsoft Windows. In 2000 it was ported to the PlayStation by Teeny Weeny Games, the resurrected form of the already insolvent Perfect. A port for the Sega Dreamcast was developed the same year but never released. Pratchett was consulted on the story and wrote some of the dialogue; he was credited in-game for causing "far too much interference." As it is a film noir parody, the game's protagonist Lewton frequently engages in hard-boiled soliloquy, or monologue.
