Wow nerd boy, you forgot about the andriods, 17, and 18.... Tien? Yammcha? Captain Ginuy? Adult Gohan?
Show some respect to your elders, first of all. Second of all, allow me to answer all of your responses (like an adult...you ought to try it sometime...):
Androids 17 and 18; so we're going to add two characters with infinite energy? Good balance. Maybe it will be balanced out by the fact that neither of them have enough distinctive moves worth animating into the game anyhow.
Tien; how the hell are we going to implement some of his signature "multiplied" copies of himself? Other than that, he's really not all that spectacular. If it really bugs you that much download a Tien model and replace Krillin. I'm sure you won't miss him, since I think you originally moaned about that model anyhow.
Yamcha; same as above but add to it the fact that I really don't want any more kamehameha waves flying around then there already are in the game.
Captain Ginyu? What's the point? So you can switch with one of the original 9 characters, and make those poor losers be stuck playing as Ginyu? hehe.
Adult Gohan is the only suggestion with merit here...but I don't see why anyone would want to keep Teen Gohan, which suggests a model change and not a new character class, which sort of defeats the purpose; he'd have all the same attacks, no?
(PS...Next time, please refer to me as "nerd MAN," if you don't mind)
