So Gran Turismo 5 finally came out in the US. The game kicks ass, I have to say that's the best looking car game ever made. The graphics finally are pushing the PS3 to what is capable of doing... Some cars look like actual pictures of them, the shades are insane. The recreation of the cars engine noise is very accurate and so is how the cars accelerate and handle.
The downside is that yes the game lacks that GT character that their games usually have. And the races are not as exiting as the previous games. But we do have online playing which is amazing, although they have to fix a few bugs on it.
Overall I say buy it you won't regret it, yes the issue that is a demo and not a full game is debatable, but still for the price is pretty damn good price.
