High Quality Content by WIKIPEDIA articles! Major League Baseball is a sports video game released in 1988 for the Nintendo Entertainment System. It is notable for being one of the first video games licensed by Major League Baseball, although it was not endorsed by the Major League Baseball Players Association. Without the backing of the player`s association, the game could not name the actual players, although it was able to use their numbers, thus accurately portraying the contemporary teams and their rosters. In doing so, it became the first baseball game for the Nintendo Entertainment System to carry official Major League Baseball licensing and lineups.
