Once the shiny veneer peels off, there's a lot of cracks in the foundation.
-Great roster updates and the character models are very detailed for the most part.
-Career mode is long.
-Customizability has been improved.
-Addition of legends like Severn, Royce and Pulver is fun.
-Plenty of unlockables (movies, cards etc).
Negatives:
-The AI is randomly set to 'Impossible' on career mode.
-Submissions are impossible to perform on the AI.
-When you're trying to work for a submission, you often accidentally KO your opponent during transitions.
-Big Nog should be able to submit Kimbo Slice.
-The degrading stats in career mode is quite possibly the worst addition possible. It essentially means you have to babysit your character to ensure you reach stat milestones. Horribly tedious and totally unnecessary.
-Connecting for online gameplay is about as successful as me impregnating Marisa Miller.
Overall, I enjoyed the game for the first few hours but the negatives quickly started outweighing the positives and I simply don't have the patience to try to play online any more.
I enjoyed most of my first run through career mode, but because of all the babysitting, random spikes in difficulty and pointless ground game, I would say this game is worth a rental if you're a fan.
