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.

During the 18-week, 4-day period, there was no free agency and training camp, and players were restricted from seeing team doctors, entering or working out at team facilities, or communicating with coaches.  The end of the lockout coincided with the formation of a new collective bargaining agreement prior to the start of the 2011 regular season.
