Lol(No offence),you got 4 already?
This has been suggested,I think they're working in something similar to that suggestion for 0.4.
Btw,Real gta?
It requires good computers because of the increased polygon count,and along with mta it would have a dramatic effect on people who have slow computers,since mta already pumps the engine to the limits.
Besides,it has a bug(That suposedly only happens in 0.1 of the computers),where the game gets bloody slow when a certain car(It's random after installing,and stays with the car that was choosen until reinstalling)comes in the screen.
Still,it's a great mod,I love the cars=P
