Jimmy's not going to graduate at 15 or 16. Even smart people like myself couldn't pull that off.
I have said, and continue to say, that any sequel to Bully should have a whole new cast of characters and a new location. We've seen this, explored the shit out of it. Time for somewhere else.
I'd like to see a normal dysfunctional High School, maybe set in Suburbia, where you could leave from your house each day to go to school, and then return. Hang out at the local eating joint (aka "Back To The Future II"), go visit friends at their houses, have back alleys for fights, different sections of town for the different cliques, more HS functions (Theater, Prom, etc), and definetely a better male/female ratio.
