For the game idea, I've always thought that Bully and The Warriors should be meshed into a single game, with some elements of GTA incorporated. Basically, the beginning of the game is very similar to Bully in terms of pacifying all the local cliques, but without the backstabbing of a person who pretends to be a friend.
Later, after a person akin to Cyrus from The Warriors invites the main character to join her network of gangs and gets turned down (since the protagonist is anti-corruption), most of the gangs in the city turn against the protagonist and the cliques under her authority, and she must use all the followers she gained to clean the city of its corruption and bring down the ringleaders of it all.
Gameplay is similar to Bully, but the city is divided into different neighborhoods, like The Warriors, with a central hub (similar to the "Kingdom" of the first Assassin's Creed). Cars can be driven in the central hub, but when entering a neighborhood, the car is automatically parked somewhere until you want to leave. Violence would mostly remain fist-fighting, but with the ability to play as different characters mainly, but not exclusively, in flashback missions similar to The Warriors.
Of course, random free roam activities should be expanded, and I personally thought there should be a punishment mini-game where if you get busted by the police, you have to survive an inmate onslaught when in prison.
