Polyphony Digital has announced that it has extended availability of the Gran Turismo 5 Prologue demo on the Japanese PlayStation Store by an additional fortnight.
The demo, previously scheduled for removal on November 11, will now remain available for consumers to download until November 30; as such, this also affords gamers in western territories additional time to download the title, which can be down by creating a Japanese PSN account.
Prologue is the precursor to the final retail release of Gran Turismo 5, and includes a total of 50 cars, five tracks, in addition to full online multiplayer functionality for up to 16 players. The game will also support 1080p HD resolution.
Gran Turismo 5: Prologue is due out in North America on both PSN and Blu-ray disk this winter.

its a crap demo anyway

Legend-SAM...you may not like it because GT is not your typical NFS, juiced, or burnout. it's just like a real driving simulator because everything acts like if it was a real car unlike other racing games.
i am hoping that the gran turismo 5 prologue will be released in the retail version in the usa.also it is kind of wierd that they released a demo of a demo.LOL.PSN id:windninja123
