1. I think that they should have some small boost but to keep in balance something not to grand. Andriods I think should have a higher Ki level actually cause they have endless Ki or perhaps for them ki attacks cost less ki. Saiyans should have a zenkai bonus but a limited on, having a saiyan double skills each time he almost loses could be problematic down the road. I agree the humans could have a higher ki pool to reflect better ki control and kaio-ken might be needed to keep things in balance in the long run. Half Saiyans I would guess should level up faster perhaps the others.<br/><br/>2. I think we should start off with two specials each having unique abilities, such as doing a + for damage or being able to chain together multiple attacks<br/><br/>3.Whatever works<br/><br/>4. I think that you can have saibamen, they would work very well, plus they do come at different levels, the SNES DBZ RPG game used saibamen as the pre-raditiz and pre-Vegeta, Napa foes for when a player explore different colors being different strengths.<br/><br/>5. I don't think there should be a difference except for half saiyans leveling perhaps a bit quicker. I think having them level differently would only mess up the balance in the long term anyhow. I think it should also matter who they fight and such, perhaps there are multiple fights even before the major battle.
