Tecmo Super Bowl (テクモスーパーボウル Tekumo Sūpā Bōru), 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 the 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 Teenage Mutant Ninja Turtles (often shortened to TMNT or Ninja Turtles) are a fictional team of four teenage anthropomorphic turtles, named after four Renaissance artists, who were trained by their anthropomorphic rat sensei in the art of ninjutsu. From their home in the storm sewers of New York City, they battle petty criminals, evil overlords, mutated animals, and alien invaders while attempting to remain isolated from society. The characters originated in the Teenage Mutant Ninja Turtles comic book before their expansion into a cartoon series, films, video games, toys, and other general merchandise. During the peak of the franchise’s popularity in the late 1980s through the early 1990s, it gained considerable worldwide success and fame.
