UFC Undisputed 3 is everything you could ask for in an MMA game
One thing THQ got down great was the technique in the striking and the ground game which is an area other games developers failed in. Also with lots of modes to keep you busy from career (my personal favorite) to tournament and champion mode. This game is overall the best MMA game to ever hit the market and although there isn't much competition to compare it to the game clearly blows all comp out of the water.
+ Great action
+ Very fun to play
+ High replay value
+ Good graphics
+ Technical entities of MMA on point
- Gets a bit repetitive
- Knockouts are a bit too common
