Sadly, this "updated" version of the neat demo for Gran Turismo HD doesn't come with any special tracks or added options. It fixes a bug. Apparently, a 700MB bug. That's right, no patches, but you've got to re-download the entire thing. Not only that, but doing so erases all your track and drift records. It's... kind of a slap to the face, Polyphony. Why? I was in the top twenty for something... well, probably not anymore, but at some point I was.
Oh! We never told you the bug. Here's the big problem: the bug caused the time to stop before you got to the finish line. That's it. Download the new version at your own discretion, everyone!
