Sorry but goku in the game... I don't want to see a light goku, goku would just rape everyone, he would make madara, hashirama and all the tailed beasts his pets...
I dont agree that Goku would rape everyone. You all ASSUME that the whole fight is pure brawn sadly.
We all learned in Naruto that the weak can push back the strong with the right tactics. For eg since Goku is simple minded he would easily get caught up in a genjutsu.
Goku's only advantage really is that he could level the entire planet and still survive in space but otherwise he would have a tough time.
Its kind of plot hole in the dragon ball series theres evidence that suggests they can but theres also evidence that says they couldnt.
Ex.Bardock litterally flew into space to fight Freiza. However In the series when Planet Namek was going to blow up Freiza stated he could SURVIVE in Space but Goku could not. This could've been a bluff but who knows.
Theres other examples to but those are just a couple. I personally think they could stay in space for a long period of time but not survive there.
