You'll enjoy this, if you're a Gran Turismo devotee who demands as much hyper-realistic track action as possible – and simply can't wait for the full release. There's no doubt that the list of cars, mind-blowing graphics and fantastic gameplay ensure that Prologue would be a decent product in its own right if the promise of the full game wasn't so forthcoming. Bear in mind, also, that downloadable updates arguably negate the need for a product like this even more, and it's expensive for an extended demo. One for the hardcore fans only.
