what would be a good idea is say you join a gang in multiplayer and then decide to leave that gang could then have the choice to let you walk free or eliminate you maybe you could rob other people or even other players could choose to put a hit out on you and whoever kills the target gets cash off of the player that put out the hit just thinking out loud
i would love to see the return of quads like in san andreas and maybe more improved sounds on the motorcycles gta iv motorbike sounds just wasnt realistic
