Surprisingly fun combat system with a few career flaws.
The career mode menus get a little tedious to click through, and like in most games like this, the "calendar" is a little pointless, but when it comes time for the fight, it pays off. The commentary is pretty good as well. Joe Rogan and ... that other guy have different things to say for every fighter, but there are some glitches like your fight being called the main event, when it isn't. It's a little too hard to submit your opponent, even if you're submission skill is way up. Other than that it's a very realistic fighting game, standing and grappling.
A few issues prevent this game from having a 9, but if you're an MMA fan definitely check it out.
