oh boy, what a hard question !

but i am a race fan, and have 2 favorites:

at first:

1> OutRun 2. i have played the arcade version more than my wallet wanted, and have played the demo on xbox to death (no, its not damaged or broken ), and i know for sure that this game gives me the same happy feeling like its almost 20 year old brother (OutRun 1986) does. yeah, i even play the orginal on my sega saturn.

2> burnout 3. for the first time i find the input of EA a good thing for the game. exept for the music, this game has it all: sharp controlls, and even sharper graphics. no popup, and no slowdown noticed yet. sometimes the car' s (especially the faster one' s) can get out of controll, and this is why i like outrun 2 more, becouse of its even more sharper arcade handling. but the speed of burnout 3 is really nothing less than astounding !

but like i said, if i HAVE to choose, OUTRUN 2 all the way baby !
