Nah, I wouldn't like that at all, having a nerdy guy. It's gonna take away the fun of beating up students with the newest awesome graphics and maybe engine. I have a good time fighting in GTA IV, a game from 2008 and there were like a total of 5 attacks or something
. Not sure about the fighting style thing, I always liked how some characters have their unique style(Russel, Jimmy, Gary). And I remember reading that the people you fight with were supposed to get bruised up, like in the boxing matches. I'd like to see that. And it would be cool if he would be a little more 'flexible'. I don't mean that he has to know parkour, just enough to jump over taller fences, being able to dodge a hit while running, etc, because everyone can do that when in a dangerous situation.
It would also be good if the protagonist is left with a more open or double personality, like Jimmy.
