I was under the assumption that the president of UFC, Dana White forced the majority of his fighters to sign exclusive contracts that prevent them from being involved in other fighting games. While there are still plenty of fighters from other promotions that can be featured in the game, I doubt the game can be successful without a roster packed full of UFC stars like Chuck Liddell and Brock Lesnar. Maybe EA Sports will get a taste of their own medicine after buying the rights to the NFL and creating a monopoly with Madden. I want my NFL Blitz back! Damn you EA Sports!
