I was always a fan of Gran Turismo over Need for Speed, but I haven't played many recent Need for Speed games. Gran Turismo always felt more realistic to me. Minus the fact that you can't wreck your car, I was always sad about that
Need For Speed is always fun... you can upgrade any car with bunches of stuff...
if you should get Need For Speed, get all of them and beat them 1 by 1
Need for speed pro street is one of the most realistic racing games that I've played, you can wreck your car, you can't take hairpin turns going 90. Need for speed also has a story line to go along with it .
