Games that should have been released

Being a fan of American football, I have always wished that some enterprising developer could have released USFL and CFL games for a system like Gamecube, Xbox or Dreamcast. I fondly remember the 3 or 4 years of USFL in the 80's and closely followed the league in its heyday. Also, I follow CFL as much as I can in the lower 48 (recently watched the 100th anniversary Grey Cup Game between the Argonauts and Stampeders), and wonder why no company ever did a 'Madden' type of game for that league complete with its unique set of rules. I read a couple years ago that a company did release a CFL game for PC's in the late 90's, but what are the chances of being able to run that on a Windows 7 machine?

That would be cool! I used to watch Canadian football in the 90's when we had a seven foot satellite dish. Also followed the WWE football. Although it was short lived.
