The one thing I'm really worried about is the driving physics. Hearing them being called "arcadey" does not make me happy. While GTA4's controls were on the sloppy side, all they needed was a little tweaking here and there. If you say it drives like Driver: SF, I can handle that.

...No, I'm not very creative when it comes to this sort of thing.
