is it any good? I hated the prologue yet enoyed the games of the past
Well I think it's very good, but I also liked the prologue. As you'll expect the graphics are pretty impressive as with each version of Gran Turismo to it's generation. Cars are in high numbers with a good selection of racing track including popular ones like the Nurburgring, Monza, Monaco, Laguna Seca, Top Gear test track and many many more.
There's plenty to do other than just straight up track racing. You have rally(dirt, snow, road), karting, Nascar, Licenses, special events etc.
There is also a B-spec mode, were you are a kind of race manager. A bit boring to be honest, but can get you prize cars and big money.
Online is okay, connection times are pretty slow but it's not bad. But it's early doors yet, many updates will come with time for this game.
Custom soundtracks can be added for during races. Just upload it to your ps3 and BAM, your driving to Oasis.
I give it 8.5/10 so far, definately recommend it. Just debating wether to get a wheel for it
