Super League '91 is a baseball simulation game, and the sequel to Super League (a.k.a. Tommy Lasorda Baseball). The game plays much the same as its predecessor, and includes Pennant Race, Open (Exhibition), and All Pro game modes. Unlike its predecessor, this version features an official NPB license, and thus includes all 12 Central and Pacific League teams, complete with player names and stats from the 1991 season. A reworked version of the game that includes audio commentary and MLB teams was released internationally as Sports Talk Baseball.
