Baseball Simulator 1.000 — About this game
Choujin Ultra Baseball, released in English as Baseball Simulator 1.000, combines conventional batting, pitching, baserunning, and defense with spectacular Ultra Plays. Ultra teams spend a limited pool of points on snaking pitches, explosive hits, super jumps, and other special actions. Exhibition, multiplayer series, season, watch, league creation, and detailed team editing modes provide substantial depth even when the fantasy abilities are disabled.
