Nice idea, however some serious flaws
On the plus side you have plenty of cars, decent tracks, nice touches such as the cars gaining more dirt on them as you go around and the fact you can end up with ruts in the road if all the cars follow the same path.
However, it has to be said, with a controller its neigh on impossible to drive in a straight line. You end up swinging from side to side in a vein effort to regain control.
With a steering wheel however, its a bit easier and you do get great feedback and its a lot easier to drive.
However you need to have decent driving skills to catch the slides, luckily I have but my m8 (who isn't bad at GT4) simply could not get on with the game, so accessibility is a question mark.
However, the game left us both cold. Even if you did win, you just didn't feel like you had achieved anything. I don't know, its a hard thing to describe.
The physics are also a bit suspect, I've never seen a bush that was has hard as concrete and causes you to spin 180 degrees when you slightly touch it.
It ended up being a frustrating experience.
If this game does interest you, its best to rent it first to make sure you like it, don't waste your money by buying it as you may end up getting as frustrated as us!
Oh, and someone needs to tell Sony about 'menus' - just to have a quick race you end up needing to go through about 5 screens, selecting track, car, car setup, car colour etc...
Just one or two screens with drop downs or alike would be have been better!
