I think we should have more shops and more cars/ bike and houseing etc ..... Police bikes, ambulance bikes, clothes shops , Hair dressing shops, more houses/ Flats
Its getting abit borining doing the same things over and over again .
There is already a thread for this: "Roleplay Ideas".
I would enjoy more buildings to go into. More hospitals, more clubs. A mall like in Vice city. Maybe some grocery marts.....
BTW - you can keep wanting those things from GTA TBOGT. It doesnt mean you will get em. Good luck with said wishes lol.
R* is working on GTA V and I doubt you will see anything else for GTA IV or TBOGT anytime soon.
