ok, i'd make a clone of gta 2 bacing it on street life, you know gangsta's and stuff like that. The main character would be a bad ass runner way. Hes only 17 and he have to make a living do jobs like killing and delivering. It would be different to gta cause you would have to say a way from the cops the hole duration of the game apart from free mode. free mode that rule wouldn't apply. You could all so play the way you want having options that will efect the duration game. Like do you want to be street racer or a gangsta or just a thug and ud have more freedom then gta:sa (in 2d). Thats mine.
