This is turning into another GT vs Forza thread...
But anyway, no. I love GT, and I will keep playing, specially because the game will keep on being updated and improved. Can´t wait what is to come. Also, there is something about GT that mekes me want to play over and over without getting bored. Even if its just cruising around a track.
But as soon as I get my christmas bonus, I´ll get me an Xbox and Forza 4. That game looks like fun.
