I really hope they make a good UFC game soon. Wasn't a fan of the last two or EA MMA. Actually UFC on the Dreamcast is still my favorite MMA game.
Personally I kind of think they should stop putting the whole roster on the game and just use the big names. Focus more on making the fighters actually fight like they do in real life. And make the movements seem realistic and not so jerky.
