Well in my opinon it wasn't that great when it first came out but they have been updating it the latest update to 1.05 makes it as good as gt4 but not better the only added bonus is top gear test track but you have to win a silly combi bus race to get it which took me hours but worth it, hopefully newer patches will make it better, i am a fan of gran turismo series and a couple of things let me down the b- spec is not available for endurances as there is proper a and b spec mode compelty seperate from each other so to do the endurances you have to the time to spare, and a little niggly problem no odometer, even though the game records mileage, most of the premium cars with the proper cockpit layout don't record it which is silly, could have been better, but i think its primo anyway, haven't stop playing it, much to my other halfs dissapointment, It is worth it but keep an open mind
