I want the cops to do more than spawn every block when I'm being tailed. I want them to use tactics. I don't think it's right to have every single cop notice me on sight. I also don't think you should get a wanted level unless you do the act in front of a cop. Enemy gangs shouldn't be able to recognize you with any car you drive. If you drive your gang's car and it's an enemy of another's I want them shooting at me. They shouldn't, however, recognize me on sight.
I want to be able to trick the police. Someone on a gta board passed around this idea. Imagine being chased by the cops and you're in a black car. You bail and they don' thappen to see you bail. A similar car goes driving by and they chase after that one for a while. I'd like to be able to trick these guys ala MGS.
If I see shadows, I want to be able to hide in them until it's cool to come out. If I murder people randomly on the streets a lot, when I get to my safe house sometimes I want to make it feel as if someone ransacked the place with a warrant.
I'm pretty sure they'll go for something different, blue. The potential here is high, and I feel R* will deliver. The trailer in general gives me a completely different vibe than past games and I'm sure thta's what they were going for. The most important improvement they can make is better AI. As much as I love the cop chases in the game, they all play out the same way: cops come out of fucking nowhere, chase ensues, ad infinitum. I want more realism here to make them more dynamic and open ended in the choices I make.
