With four million copies sold, it was a runaway hit. The developers probably could have phoned in a new sequel with a couple of minor extra features and a roster update, but they didn't just stop there. UFC Undisputed 2010 sports a huge list of new features in just about every area of the game, as well as a ton of new fighters and moves. Sports games often take heat for having relatively few changes on a yearly release cycle and still costing full price, but luckily for us, this is much more than just a yearly update".
