UFC Undisputed 2010 - Microsoft Xbox 360

The grappling system feels more responsive than the first Undisputed, making submissions actually satisfying to pull off. I've been playing through the career mode for a week and still finding new moves to unlock.

The striking system feels way more responsive than the first game, and the career mode actually makes you care about your fighter's training between bouts. I've sunk hours into building my guy up from the undercard to a title shot, and it's still pulling me back in.

The career mode is deep enough to keep me coming back, and the new ground-and-pound controls finally feel intuitive. Even after unlocking everything, I'm still finding new ways to finish fights.
