I always figured perfection dealt more with character traits like perfect love, perfect patience, perfect faith, that sort of thing. I think we can still be unique individuals though.
But to take into consideration the all powerful factor, I'm picturing a video game type situation. Where I can manipulate my power or my speed or my strength. And then go up against other players who have done the same sort of manipulation. But you have a limited quantity of power points or whatever to divide up between those different characteristics. And of course you need rules, so no mind reading, no artificial manipulation of the ball, etc.
