1. License plates with actual numbers, not LIBERTYCITY.
2. Traffic that actually notice your there. Too many times (every time) have i stopped at a red light and been rear ended by the twat behind me, or they just overtake me and scratch up my hot whip.
3. Cabs in IV picked up random NPC's, but i tailed one for 45 minutes (yes i have nothing better to do) and it just went around one block in north holland and the passenger never got out. I would like to see cabs actually dropping homies off.
4. Crime scenes appearing after you've left buildings/areas. (Saw this in mafia 2, you rob a gunshop and then come back 10 minutes later and its taped off.)
5. A few read dead redemption features but modernised - bounty hunting, roping up randomers and putting them in the back seat/trunk, bribe the 5-0 to fuck off on 2 stars or less & purchasing and then owning a car that spawns near you... (cant whistle for cars) ...after cutscenes.
