in some way you should be able to choose if you want to have seatbelt on or not
if you wont use it you should probably fly trhough the windshileld and lose more than 50% of your health
you should shoot out from the car like you do in multiplayer on SA on the ps2
real tools like in VC, you can run out of petrol also real damages on cars and bikes like loosing wheels and when you droop the exhaust pipes the car should make mor noise and the coops should have speed controls and speedcameras should be placed on some places slike the uniqe jumps but on this you have to get speed to be photoghraphed by the camera
realistic injuries like if you get shoot in the leg you will have problem walking and wheelshairs should also exist
btw speedometer is a must for this game
you should also be able to choose the guy you want to be like you could in gta1 real cars and real names for them.
MORE BIKES if they could remove the planes they could put more bikes in the game
