Similar to other football games of the time, the gameplay follows a slightly simplified version of standard American Football rules. Players have the option to play as different teams, as well as select number of players. Although the game does feature Joe Montana (as the title respectively says) as a playable character, since Sega did not secure the rights from the NFL, teams are named generically after US cities, meaning Joe Montana is the only real player in the game.
