I think the mood of the game that the graphics portrays is perfect.
BUt there should be some improvements in the graphics I think. Firstly to improve on GTAIII, and secondly to make it feel as if it's not just an add on of GTA III.
Unless that's what it is
Either way, I'm sure there will be more goodies. MOre radio stations. More variety (even though there is more than enough). That would be nice. I love just cruising listening to music.
