I know this would be hard to do but it would be cool if each perosn got to pick there own character....Goku, Gohan, Vegeta etc. and stick with that person for everygame. They would start at a certain pl and only know melee. As they gained power level they would learn each move. Also your power level would be saved. And gaining power level would be slower so it would be harder to get strong. Hopefully this will be possible but i doubt it.
