Anyway has anyone seen the Gamespot hour long video on GT5, ive only seen 10 mins myself but they certainly dont sound too enthusiastic for it. The pretty slow loading even after full install, having to install the same thing twice, only premium cars having interior views, only being able to take photos of premium cars, the car he was driving at the start he commented looked a bit ragged and it didnt look all that.
So its reviews could end up being nothing special at all.
