If you have been drooling over Forza 2 because you do not have an Xbox 360, this is the game for you. If you love racing sims, this is the game for you. BC Magazine highly recommend Gran Turismo 5 Prologue with some minor caveats. While no racing sim has physics down pat, they still prefer the feel of Forza 2, though this game exudes quality in everything - especially the handling of different makes and models.
Considering BC Magazine's dislike for previous GT games, they are very pleased with how Gran Turismo 5 is shaping up. Things look good for when they can erase the word "Prologue" from the box. This is the taste that Sony's fans need right now. Well worth the purchase.
