Street all the way the adrenaline you get when cops chasing you and you're trying to lose them, the tight turns and the way you need to drift just right to successfully turn without losing a lot of speed
OH and you can have a variety of cars with alot of modifications as well, paintjob, engine, NOZ!, spoiler, rims, and body, etc. INCLUDING NEON GLOW! i'm addicted to that shiz! LOL
Tracks get boring way quicker than streets. I like the street racing where there is shortcuts and ramps and all that good stuff
I think games like nfs are not realy racing games is allot about getting lucky there's no other trafic coming. I would call that driving games. Games like Forza, f1 i prefer tracks. Games like burn out,nfs i like streets.
I prefer streets, I love having the police chase me, then avoiding road blocks and making them crash into stuff. xD
