I very much dislike GTA 4 because of the realism. I really want to be able to screw a hooker in a dark alley, shoot her, take my money back, instantly switch to a Molotov Cocktail, hurl it at a cop car, kill the cops, take the flaming cop car, run over hundreds of nameless civilians, run from the cops, and enter my house and be acquitted of all charges. It'd be nice.
