Come on guys, this is going to be sooo good! At last, a new GTA - not just a GTA: 'whatever'.
Things I'd like to see:
1. Remember those random Ice Cream vans and such, that when entered started a mini mission? Bring em back.
2. Car customisation. More clothing options.
3. Planes. Airliners. Parachutes. Rocket packs.
4. More mini games - GTAIV didn't have enough IMO, bring back the gambling, horses, slots etc...
5. A good coherent story, slightly more easier to follow. I'll be honest, I struggled last time.
6. More classic homages to classic vehicles.
7. The buddhists!
