Overview
Pro Yakyuu World Stadium (""Professional Baseball World Stadium") is a baseball simulator from Namco and the first of the World Stadium off-shoot series of their Family Stadium, or Famista, franchise for the Nintendo Famicom/NES. The World Stadium games are those released on a non-Nintendo system.
It was released in the Arcade and for the PC Engine in 1988 and was the first baseball game for the latter system, narrowly beating the release of Hudson's World Class Baseball (JP: Power League) by a month.
