Discworld is a graphical point-and-click adventure game developed by Teeny Weeny Games and Perfect 10 Productions and published by Psygnosis in 1995. This game is roughly based on “Guards! Guards!”, the eighth Discworld novel by Terry Pratchett. You take the role of Rincewind the Wizard (voiced by Eric Idle) in a world called the Discworld. It’s actually a flat disc carried on the backs of four gigantic elephants, which themselves stand on the back of an even larger turtle. This game has been released for PC MS-DOS, Apple Macintosh, Sony PlayStation and Sega Saturn.
