I only play GT3 once in a blue moon if the kids put it in for some reason. What I love about that game is the old school transition and menu music. I LOVED that (maybe only in retrospect).
Speaking of music and sound, I've been playing NFS Most Wanted recently (kids got it for Xmas) and the exhuast sounds on that game ROCK! I wish GT had better exhaust note modeling. I mean if they could can the real sound that the Z and G35 coupe kick out now, I'd be a happier guy. It does sound a bit better sometimes from outside the car, but still not good enough...
