Lets break it down
Graphics;

why does francis look like nate diaz?

Gameplay;
Ai is shit, either they don't throw a punch, or block everything and you cant touch them. They automatically lose to submissions. Oh and the AI never lose stamina
The games control mechanics are just pure trash. The forward pressure dynamic is the only great thing, but also bad, because people can just spam any button and you cant avoid shit, " head movement " control doesnt do a damn thing when someone is spamming, if it even works half the time. Having no parry causes this
The stun mechanic... stun, stun, stun, stun, stun, stun, stun, stun, knockdown, knockdown, knockdown, knockdown, stun, knockdown, finally KO.
The wrestling and takedowns are terrible, its all reliant on stats and not on reflexes or timing. Submissions are once again, automatic wins if you have a higher sub stat.
Tim Johnson ( fatty ) has abs in the game
Another shitty EA game released before its finished, dont buy this pile ( play ufc 2 if you wanna play a mma game )
