Gran Turismos have always been about realism, and quite frankly, I suck at any game that has even a hint of realism in it. But I've come to enjoy Gran Turismo 3 A-Spec (although i don't own it), because it just feels fun and I've gotten a little better. Also, Ridge Racer V is also fun... but then again, these games while being very good in executing and fun factor, don't really compare in terms of overall enjoyment to those arcade racers. Yes, I was mainly referring to the Burnout series and that... gah, brain malfuntion.
