TTGamer published a review of the Gran Turismo 5: Prologue realistic car racing game for the Sony PS3.

The review is done with an early preview edition. Gran Turismo 5: Prologue will ship in the U.S. starting April 15th for $39.99 on Amazon.com.

Quote from the review: "As the name implies, GT5 Prologue is an introduction/preview to the full product set to ship most likely in 2009. It offers a few cars and tracks to play around with in the new engine, as well as some new exclusive features which are enabled by the next generation power of the PS3 system.
Where GT5 Prologue differs to the GT4 Prologue game is the meat and potatoes. There is a heck of a lot more to do in GT5 Prologue than before, and you will spend hours upon hours in this game."
