NES Play Action Football is a sports video game developed by Nintendo for the Nintendo Entertainment System. Lacking an official NFL license, the game features eight teams named after actual NFL cities, utilizing rosters of real players from the 1989 season through a partnership with the NFL Players Association. Players can substitute backups for key positions as needed during gameplay.
Nintendo takes its game to the gridiron with NES Play Action Football. While Nintendo did not get the NFL license for this one, it did secure the license of the NFL Player's Association, so the 8 teams to choose from (all named after the appropriate NFL cities) are all stocked up with real pro players from the 1989 season. You can even substitute second-stringers for the `skill` positions (QB, RB, WR, TE, and FS/SS) when your starters get tired.
