Ultra Baseball, or Baseball Simulator 1.000, is a series of baseball sims from Culture Brain. Most are defined by their inclusion of superhuman abilities for the athletes, though these are usually restricted to a special league.
The first two games in the series, Choujin Ultra Baseball and Super Ultra Baseball, are best known in the West as Baseball Simulator 1.000 and Super Baseball Simulator 1.000. The subsequent four games in the series were only released in Japan.
The six games include:
- Choujin Ultra Baseball (Baseball Simulator 1.000)
- Super Ultra Baseball (Super Baseball Simulator 1.000)
- Ultra Baseball Jitsumeiban*
- Super Ultra Baseball 2
- Ultra Baseball Jitsumeiban 2*
- Ultra Baseball Jitsumeiban 3*
(* = These games were all officially licensed by the Nippon Professional Baseball league.)
