Mutant League was an animated series based on the videogames "Mutant League Football" and "Mutant League Hockey" which aired from July 2, 1994 to February 24, 1996.
 The show ran for two seasons, with the second typically incorporating more poignant stories and issues, while the first seemed somewhat hodgepodge with little regard for continuity (the Monsters have one win streak that ends twice, for instance).
 There are forty episodes in all, thirteen in Season 1 and twenty-seven in Season 2.

WWE 2K Games (formerly "WWF SmackDown!"
, "WWE SmackDown!"
, "WWE SmackDown vs. Raw", and WWE Games) is a series of professional wrestling video games based on the American professional wrestling promotion WWE.

 series is among the best-selling video game franchises with 47 million copies shipped as of 2009.

 THQ and Yuke's Future Media Creators consider one reason the series has remained so popular is due to series bringing "WWE programming to life through a host of key new features, extensive rosters with WWE's most popular Superstars, incredible graphics and engaging action in and beyond the ring."
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 National Football League and the 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 meant that no rookies taken in the 1991 NFL Draft and no player team changes executed before the start of the 1991 season were added.
