Ultimate Basketball is a NES basketball video game. It was released in September 1990 by American Sammy.
The game plays like a conventional sports video game. The player chooses from a list of seven available teams, and controls five players on the team on the court, though only one player may be directly controlled at a time. There is a championship mode and a single game mode in the game.
The game is unlike later sports based video games in that doesn't use real professional or college basketball players. The players a player may select for his team are entirely fictional, as are their statistics.
It was possible for so many players to foul out that only three or four were on the floor at the end of the game.
