NFL Challenge was a computer game, released in 1985 by XOR Software. It was notable for being one of the stronger football simulations of its time, with statistical models to not only the NFL season, but also the outcome of a single football game. Being one of the first football games for the PC it is still considered one of the best requiring 10 man-years to make and over 30,000 lines of code.

ESPN used the simulation in 1988 for a program called NFL Dream Season. Historic NFL teams were computer-simulated against one another in an 8 week season, then playoffs, then the "Dream Bowl". ESPN used the computer simulation results to play back the game using NFL Films footage, to make it appear that one was watching an actual game. The 1978 Pittsburgh Steelers defeated the 1972 Miami Dolphins 21-20,

The following year, ESPN broadcast Dream Bowl II, with the defending champion Steelers pitted against the then-Super Bowl Champion San Francisco 49ers. Even with John Stallworth out early in the game due to an injury, the Steelers defeated the 49ers in overtime, when Joe Montana was intercepted around mid field by Mel Blount, who returned the interception for a touchdown. Steve Sabol, NFL Films president, said he disagreed with the simulation result, feeling that San Francisco had a better team.^{[citation needed]}

XOR made available the Dream Season disk after the show's run, with the actual teams used by ESPN's program.

The company went out of business in the early 1990's, after advertising NFL Challenge Premium Edition, which never made it to market. There were several customers who had prepaid for the product, only to never receive the game.^{[citation needed]}
