Gran Turismo fans can now grab a free demo of GT5 Prologue by logging into the Japanese PlayStation Store right now. You will need to create a new PSN account and register as living in Japan (just Google - create JAP PSN account)... its all free.

You get a small selection of cars and use of the Suzuka GP track (used in the formula 1 season until this year), against 15 other cars.

I have never seen a game that looks as good as this. The cars and drivers look photo-realistic on a full definition HDTV.

There is also a sample of GT-TV channels that allow you to download tv programmes all about cars and racing.

If you are a racing fan, this is definitely worth 20 minutes of your time to set up a JAP account and download the demo.

This feels like the first game that has unlocked the potential of the PS3 cell processor.
