Gran Turismo 5 has a prologue? You download on to your PlayStation 3, rather than buying it, It is still in the making and I don't think there is a due date for the full game. Gran Turismo, if you don't know, is known for it's incredible selection of cars and graphic, oh my, the graphics are INSANE! But, not for the gameplay, I'm most certainly not saying it's bad, but there are definitely games. Need for Speed is definitely better, but not in graphics and has a very low selection of cars. And if you have any other Gran Turismo you will know what to expect times two! Sounds like fun!
