Tecmo Super Bowl is an American football video game for the Nintendo Entertainment System (NES) that was released in 1991. Developed by Japanese video game company Tecmo, it was the first sports video game that had licensing privileges with both the league it sought to emulate (National Football League) and said league's player's association (National Football League Players Association), thus allowing the game to use both the names and attributes of real NFL teams and real NFL players. (Prior games used the real teams or the real players, but not both simultaneously.) Although the game was released in late 1991, all team rosters and player attributes were based on the prior 1990-91 NFL season, which means no '91 drafted rookies and no newly signed or traded players prior to the beginning of the 1991 season were added to the game.
   The original game utilized the 1991 NFL schedule only; therefore, playing multiple seasons with alternate schedules was not possible. The game was very successful in the final years of the NES and, although more than 20 years old, it has maintained an extensive cult following.
   The main menu of Tecmo Super Bowl provided the player with options for NFL Preseason, Season Game (Regular Season) and Pro Bowl play. Team data could also be accessed from the main menu. In the original NES Tecmo Bowl, each team had 20 players on its roster, with nine players for offense, nine players for defense, a kicker, and a punter. In Tecmo Super Bowl, each roster had 30 different players. Each team had eleven defensive players, which could not be substituted, nor injured. Each team had seventeen offensive players, which included eleven starters and six substitutes. At any given time, eleven players were on the field for each team, consistent with NFL rules. A kicker and a punter were also on the roster.
   In addition to using real teams and players, TSB incorporated the full-length 1991 NFL regular season schedule for the game. The playoff format, including the Super Bowl and the post-season Pro Bowl game, was also used.
