On the surface its a fantastically polished homage to the previous GT games.
However, if you think about the state of the game for 5 minutes you can see the absolute joke that it currently is. If I wanted to waste upto £200 on a virtual car, I may take a second to consider how much time I could get at my local Go Kart track instead. I play gran tourismo to be the racing driver I can never financially be, not to effectively have a "you can't afford this" simulator.
Such promise, but needs revaluation with regards to the future.
