I watch it, don't play it. I had a game once, with my mate, his brother, who is like 25 and his mates. Had the ball, and the guy drove his head into my gut. Winded, but I stayed on my feet, and kept backtracking. Couldn't resist but give him a nuggy.
He stepped back, and I thought he was gonna knock my lights out, but he just turned away.
Never played it ever since.
