"Gran Turismo 5 Prologue feels almost unbelievably realistic in-car, where your dashboard has a fully working speedometer and odometer, there are wing mirrors and a rear-view mirror that contain images more beautiful than most other full driving games, while the engine noise changes to reflect the interior. The only odd aspect, particularly compared to PGR4's in-car view, is the absence of accurate gear-changing via your driver's hands. Weirdly, other sections of the game are at the moment graphically poor: the trackside crowds are boringly lifeless, mutely clapping and grinning on the same two-second loop regardless of your actions and the race. And, in thirdperson, even the amazing vehicles sometimes seem like shiny waxworks.
But Gran Turismo 5 Prologue can afford a few faults, being merely a taster for winter 2008's main course, and the most important aspect of this iteration is the online support. This comes in the form of races for up to 16 players, and an incorporation of Home into the interface garage". -Next-Gen.Biz
