It only asks a few questions and didn't even ask my date (I got mine from Asurion) when I got it. All it really asks for (besides your address etc) is your phone's MEID.
You get to chose from Kinect Sports, Halo Reach, Lode Runner for the 360.
I grabbed Halo Reach (a game I have been meaning to grab).
If your not going to use it or don't have a 360, I could also use Kinect Sports (Halo is for me, Kinect is for the family), PM me
Note: Offer valid with purchase of an HTC Trophy between May 26, 2011-July 15, 2011
