I'd like to see some returning characters from the GTA 3 era just because I'd like to see what they're up to now. Also, it would be cool if places like Grove Street were still around in the new Los Santos, though it probably won't be. Character customization on par with San Andreas would also be pretty cool. Additionally, I'd like there to actually be some stuff to spend money on especially once the game is finished. In GTA IV you couldn't purchase any property or buy any businesses. What's the point in having money if there's nothing to spend it on?
