Worth playing, for Gran Turismo fans only.
There is also an arcade mode where you can create a quick race by using a car from your garage and choosing a track and the type of race. There is now a drift mode which is new to Gran Turismo, it's also pretty hard to get the hang of.
There is an online mode, which isn't that great, it's really laggy at times and you can't create your own matches and there is no lobby, so if no one is in the event you won't know until you wait like 10 minutes for it to load and then the race will start and no one will be there.
The graphics in this game just look amazing, every Gran Turismo always has great graphics. The menus look really nice too. The jazz music that plays during the menus fits really nicely. The car selection is good, there are about 70 cars which include Ferrari's and some low end cars like Daihatsu's and even some tuner cars. There is not that many tracks in the game, but there are still some good tracks like the High Speed Ring, Fuji Speedway, and a cool London race track.
So, if you're a Gran Turismo fan than you should enjoy this game but if you don't know anything about the series than you probably shouldn't buy this game.
