yeah but its not realistic, if you try to brake and turn at the same time, you just slide, almost every car except for the very fastest handles like a boat and slides all over the place. its a little more realistic than the other gta's but still not very realistic at all. once you get the ferrari, porsche etc... look alikes then its realistic, except the braking and turning thing.
and online is insane, if you get like 6 people in one area with the rocket launchers and grenades, and a high wanted level so there are helicopters and tons of police cars, its like a battle zone, shit is blowing up constantly and all over the place, multiple helicopters will be falling out of the sky in pieces while like 5 cop cars are blowing up at once and debree is flying everywhere. its fun to get a fast car and drive straight into the pile of cop cars and cops being blown up and just plow through it. and if you get a ton of people playing at once you can actually use the whole city and be fighing against eachother in helicopters and shit, and being able to hide in like one out of every 10 buildings you see makes it so much cooler. i just wish you could have like 100 people playing at once throughout the whole city.
the races are fun as hell too, if you just get out of your car and get a rocket launcher and wait for the other people to come by you can blow the hell out of them, do drive by's in the middle of the race, throw grenades and stuff out of your car at other cars while your racing them. its insane.
