Fallout is a critically-acclaimed computer role-playing game produced by Tim Cain and published by Interplay in 1997. Although set in the late 22nd century, its story and artwork are heavily influenced by the post-World War II nuclear paranoia of the 1950s. The game is sometimes considered to be an unofficial sequel to Wasteland, but it could not use that title as Electronic Arts held the rights to it, and, except for minor references, the games are set in separate universes. It was also intended to use Steve Jackson Games's GURPS system, but that deal fell through, forcing Black Isle to change the already implemented GURPS system to the internally developed SPECIAL System. A sequel, Fallout 2, was released in 1998.
