GT5 Prologue is basically GT5.
Prologue is the Demo so GT5 has been passed 10mil.

That is an odd way of looking at it.  How many of those people who bought Prologue bought GT5?  That is why they are considered seperate, because they are seperate games.

lolwut im sorry they are separate games? How in the world terrible logic. They aren't seperate really it's just one is the demo and the other is the full game. Basically I always coun't the demo sales with the full game.

Answer my original question.  How many people do you think has bought Prologue and then bought GT5 as well.

And you are saying my logic is bad?  That is why Polyphony will directly only count GT5 shipments as GT5 numbers and not prologues too?  So are you saying Polyphony has bad logic too?
