World Stadium (full title: Pro Yakyū World Stadium), is a series of baseball arcade games that were released by Namco in the late 1980s and 1990s; they were spin-offs of the Family Stadium franchise, inspired by the 1986 Famicom game Pro Yakyū Family Stadium, and its sequel Pro Yakyū Family Stadium '87. Except for Great Sluggers '94, which was also released in America, all of the games were exclusive to Japan.
