Buy it you've only got full determination and a steering wheel cos you'll never end up even being able to drive it.
Though "realism" can get annoying because the car is very sensitive which I would agree is pretty realistic but when it takes two weeks to be able to drive a car and keep on the road but then to compete with AI's lap times is very hard. If you play and game after a couple of weeks and you can't do a full race in sim mode regurally there isn't much fun in it. If wanna enjoy this game just concentrate on this game.
This game is only for the hardcore driving simmer. You need a good steering wheel and play with the sensitive and other input setting as it can make a huge difference.
When you go online you can see how many people can't keep the car on the track for a whole lap. After racing for real life I don't agree it is that realistic but it is a step in a good direction.
Except for the diffuculty the graphics are nice. The graphics only use directx 8 and you can tell but it still looks good due to car models details and using directx 8 to it's full. Though to put full settings you need a beefy system but the good side is lower settings won't be noticeable.
All the options for gameplay are typical and there's not much else to say about the game.
My best advice is wait till GT Legends comes as the company is spending more money on it, the graphics will use directx 9 and it's already getting great news.
