 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 Players 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 .
