Great car game for the PSP!
I've always been a fan of the GT series and looked forward to this coming to the PSP. I use my PSP extensively while travelling (which I did a lot of last year) so it was a great buy for me.
Gameplay is fairly straight forward and there are not a whole lot of options but just selecting a car and driving or racing is just plain fun.
There is a large variety of cars but one thing I did not like was that only a certain number of cars from a certain number of manufaturers are available at any one time. If for instance you are looking to buy a Mazdaspeed6 and you don't have enough funds for it when the Mazda dealership is available, you may have to wait until it is available again before you have the option to purchase it.
Solid game. Definately worth the price for me.
