Fallout is a series of computer role-playing games produced and published by Interplay. Although set in and after the 22nd century, its story and artwork are heavily influenced by the post-World War II nuclear paranoia of the 1950s. The series 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. There were two role-playing titles in the series (Fallout and Fallout 2), one squad-based tactical combat spinoff (Fallout Tactics: Brotherhood of Steel) and one action dungeon-crawler for PlayStation 2 and Xbox (Fallout: Brotherhood of Steel). A sequel, Fallout 3, is currently being developed by Bethesda Softworks. Bethesda now owns the rights to make all Fallout games, Bethesda have conditionally licensed the rights to make a massively multiplayer online role-playing game version of Fallout to Interplay. In 2001, PC Gamer named Fallout and Fallout 2 as the fourth best computer game of all time.
