I'll admit I ripped this idea off from pro wrestling games. But I think it would be interesting to play as the referee. You get to decide when fouls are called, when to issue red and yellow cards, when to give penalties, etc. Mostly this idea was born out of the horrible officiating the CPU does, I could hit a guy with a bat and play on. But I think it would be fun to be the referee in a match between two of your friends. Just a thought.
