If there's one thing WWE video games have never included, it's the ability to scan your face and/or other images and putting them into the game itself. It's something EA video games have done in the past. It might be a good idea for it to be used in WWE '13.
Even better idea would be just make the game full body control so I can dodge punches, bounce between the ropes, kick some sweaty dude in the stomach and elbow drop his face onto a dustbin lid.
