Great Sluggers is a 3D, fast paced baseball
game that allows one or two players (at the same time) to enjoy the great
game of baseball. Players can choose their teams, control how the
players react, skill levels, type of stadium, complexity of the game, etc.
Namco included stats from the actual Major League teams and players,
lots of realistic speech, and a nice sound track.
Great Sluggers was possibly only sold as a JAMMA conversion kit.
