Test Drive Unlimited is a really great game if you love racing on a huge island or even free-roaming around. To me it looks and feels just like any of the old Cruisin' games, with the beautiful scenery and you don't even have to race to drive it. Online is one of the best I have ever seen, although I wish you could have more than 8 poeple online at once on the island (even if it is a MMO). This is a game where if you just want a beautiful car and just drive around a 1000 mile island. Some of the single player missions are a little bit tough, but not enough to throw the controller at the screen when you lose a race.
A really great factor of the game is your car cannot get damage at all, so your car is perfect all along the ride (I hated my car looking crappy after a small bump in some other games).
For new players trying to get a lot of cash, try driving a car for someone; you'll earn at least 80,000 dollars without the bonus (if you don't wreck the car into anything else or off the road), then it is at least 125,000 bucks.
All of the other racing games just put you in the streets and focus mostly on racing, but Test Drive Unlimited is for the people who want to lay back and enjoy an Enzo Ferrari going 230 mph on Honolulu Beach.
