Not bad at all, perhaps it is worthwhile for those most eagerly anticipating GT 5?
Seems that way, and even at 40$ its a bargain considering it has more content than most racing games anyways...

 ...Its gran turismo....of course we'll pay the $40,money well spent in my opinion.

Not sure but I heard from a colleague that you get 50 cars in Prologue out of a possible 1000 cars in the full GT5 next year.

Aren't there 75 cars?^ I thought so, the Eu and NA edition has more cars and an extra track each I think!

Look, this isn't anything new to fans of GT. There was a GT4: Prologue in case those who aren't interested in the GT series didn't know (in which case, I'm not sure why you are in this thread). There's plenty of game included in the $40 that GT5: Prologue is going for. 70+ cars, 6 tracks + variations, and online/splitscreen racing. For a racing fan, that's a lot of gameplay. Definitely not as much as other racing games, but enough that if you are a fan of the game, you will be spending plenty of time on the game.
