ufc is the only one i've tried. it's hard to master the controls but career mode is fun (and frustrating) but mostly fun! fight night round 4 maybe more in depth though. check which one u like better here: [url=http://www.gamepro.com/article/features/211216/ufc-2009-undisputed-vs-fight-night-round-4/]
UFC all the way man... UFC is a new kind of gameplay when final night round 4 theres other games like it. and UFC has ground fighting and standing fighting.. after thinking bout it UFC has final night round 4 aspects in it.
