Some of you may remember that last year voting in the awards got you either Civ 5 or Hitman. This year you get XCOM Enemy Unknown and an 80% off voucher for XCOM Enemy Within. You can vote here. You need to vote by the 20th.
Voted, plan on giving my XCOM copy to a friend, since I already have it. 
Way ahead of ya, already got it
Voted, but did not see any offer for a free game. Perhaps it was mailed. Still, fun to pitch in votes on these.
