Grand Theft Auto 4

I think they are just going off the last number shown, since they can't just call it "liberty city" or something. Or they are counting the last 3 games all as GTA 3 because they are all pretty much the same game. Like when Vice City was first coming out and being talked about it was originally named "GTA 3: Vice City" as sort of a tack-on extension on the existing game.
