I've played, beat and fully enjoyed GT3 to the extremeeeeees. I was so hyped about GT4 that when I played I was dissapointed. The AI sucks and because of this, it really drags down another negative aspect, the bumping physics. However, the other day I downloaded a 100% savefile for GT4 and it brought the nostalgia back again. Also, there are shitloads of cars. Should I give GT4 another go and try to beat it before GT5 comes out?
