I know for a fact that GT3 did come bundled.  I know this because I still that's the bundle I got when I bought my PS2; I still have the box in my closet.

I know GT5: Prologue came bundled in Europe, but I'm not sure if it did anywhere else.  Beyond that, I don't know if any of the other titles did.

i think Halo would win, not that i would care i dont like either, Halo is a boring game and GT is a racing game, which by default makes it boring imo

Both Playstation and Xbox fans would be very happy :)

are you a gamer? lol

Very interesting question and one that I can't really answer definitively. Halo has always had the higher attachment rate and halo 3 is by far the best selling halo games so far so this gen I'd probably give it to halo. But it'd be close.

 haha, i just beleive that racing games are the incarnation of boredom, the only ones i have liked are MK, F-Zero and Diddy Kong, i have played GT 1,3,4 and they all did an exceptional job at boring the hell out of me, and Halo is just an overrated average fps
