HardBall III is the third game in MindSpan/Accolade's series of baseball games. It features the MLBPA license, allowing it to use the player names from the 1992/93 season. It does not have the MLB license, however, forcing the developers to simply refer to teams by their cities (The New York Yankees and The New York Mets are simply referred to as New York A and New York B, for instance).
The game was first released on the MS-DOS platform in 1992. It saw a Genesis port the following year, and a SNES version the year after that.
