It is GT4 Prologue. At game spot.com they have a video that shows all the cars that are in this big demo. I counted 63 cars total, while IGN says there is about 50. The McLaren F1 is the long Racing version. I ordered the game off
www.yesasia.com and it was about $40 USD. I also ordered a Magic 3.1 mod chip so I could play it on my US PS2 but I need help installing it (don't have soldering experience). So I am obsessed. I payed about $80 just to play a demo of a game.
When the full version of GT4 comes out I am ruined. I'll flunk out of school and my girl friend will leave me.
