All this talk about ego. When I was a kid, I'd play action games on my Nintendo. When I got a game, I would usually select normal difficulty. This was usually sufficient to give me a fun challenge. After a while, I got better, and had to switch to hard mode to keep the game fun because I'd stopped dying on normal mode. I never got good enough to play on the very hard mode without getting game over within minutes. A friend of mine managed to beat the game on very hard though. That didn't bother me, as hard mode gave me a challenging and fun experience until I got bored by the game itself. For something to be entertaining for a normal individual, it has to have more possible outcomes than instant game over. Nor can it be a cakewalk, as that gets stale quickly. An even matchup is the proper difficulty level for participants to have the maximum combined amount of fun. It's not like the winner of the white belt division doesn't know that he's playing on easy difficulty when he's celebrating.
