- New story mode. I was always disappointed when the main GTA stories ended and we were left to fend for ourselves. This includes new characters, interiors and dialogue.
- Revamped multiplayer: Unlockables and ranks like CoD4 would keep MP interesting.
- More weapons.
- More cars - Smartcars, ftw. Or how about right-hand driver imports from Japan and Britain?
- A few new radio stations, or at least an updated track list.
