We're so glad to settle, in fact, that Gran Turismo 5: Prologue's release in Europe has catapulted the game to the top spot on Amazon's UK site. It holds pole position (that's #1 in auto race talk, folks) in the PC and Videogames category on the online retailer. Furthermore, Play.com, one of the largest game stores in the UK, is reporting a sell-out for initial shipments.
