Not so good
Gran Turismo has over 850 cars, wich is really cool, but there is no career mode! And the game goes on by days, so you can only buy from 4 different manufacters a day.
A great racing game
this game is fun, it has great graphics(for the psp), it sound very good and there is lots of tracks and a good variety of them, lots of challenges to test you skills at the game. There is also lots of cars and delerships.
overall this is (in my opinion of course) the best racing game on psp and one of the best games on the psp period.
