Discworld is a point-and-click adventure based on Terry Pratchett's novels of the same name. Players assume the role of Rincewind the "wizzard", voiced by Eric Idle, as he becomes involved in exploring the Discworld for the means to prevent a dragon terrorising the city of Ankh-Morpork. The game's story borrows elements from several Discworld novels, with its central plot loosely based on the events in "Guards! Guards!". Pratchett was originally reluctant to grant a licence for a game based on his novels, after the commercial failure of a video game adaptation of "The Colour of Magic" in 1986. Gregg Barnett, the game's designer, managed to persuade the writer through offering, alongside an initial design concept, to faithfully recreate elements from the novels.
