WarGames: Defcon 1 (known simply as WarGames on PC) is a video game for the PlayStation and Microsoft Windows developed by Interactive Studios and co-published by MGM Interactive and Electronic Arts (in North America, MGM Interactive solely published the game). Although both versions possess the same missions and content, the PlayStation version is a tactical vehicle-shooting game while the PC version is a real-time strategy game (similar to Jeff Wayne’s The War of the Worlds). The game is loosely based on the movie WarGames; one of the story consultants was John Badham, director of the original film.
