"When we reviewed Gran Turismo 3 we found it to be one of the freshest experiences in a long time and it earned a 96% Final Verdict. Gran Turismo 4 was measurably better than GT3 in every way, but the bar had been raised. GT4 earned an 82% final verdict, but this was based on a 10% penalty for Sony going out of their way to disable support for the Logitech MOMO Force, accepted as the best steering wheel on the market at the time. Even then, it would have only earned a 92% final verdict. In 2007, Sony has shown greater humility and GT5: Prologue actually supports the Logitech G25… In fact, rudimentary support for the clutch feature is implemented!
So what's GT5: Prologue's final verdict? 95%. Even though GT5:P is essentially a technology demonstration for the PS3's 1080p gaming capabilities, the Cell's physics calculations, and the new upgraded physics engine, the combination of these features generates a completely new experience. Because the realism of the game has been bumped a notch, the excitement and thrill of racing has come back. Like games such as DDR before Gran Turismo, and the current world of Guitar Hero and Rock Band, Gran Turismo 5 is a game that requires a dedicated controller to fully enjoy the experience."
