11. Create-a-fighter is much better
The amount of choice you have to make your own fighter is almost on a par with the amazing depth of Smackdown vs. Raw. You can tweak sliders to make every part of your brawler just how you like or even give them long hair this time. Heck, you can even put a shave in the eyebrows if you want him to look like a twat.
You're also able to move sponsor logos on your shorts far more freely than ever as you use the right stick to choose your perfect spot. This same technique is used to put tattoos on your man too.
Aside from the cosmetics you'll be able to use points to purchase different strikes, grapples and submissions that you unlock as you progress. So you can have now Lyoto Machida's trademark head-kick with any number of combination of other skills.
