An anonymous reader writes "Sony has seen fit to release Gran Turismo 4: Prologue in both Europe and Japan, but the U.S. arm of the company chose not to ship it in the States. The result? Only importers and select members of the media have been able to play the game. Thankfully a limited U.S. demo has turned up from a very non-gaming source, according to GamePro.com, who explain how to navigate through the Toyota web site and request a Toyota Prius-specific two track demo of Gran Turismo 4, completely free of charge. The demo is playable on a standard U.S. PlayStation 2 console. I wonder if Toyota made enough copies of the demo to satisfy every PS2 owner in America?" We previously reported on the Japanese version of this disc, released last September.
