There are 5 series' owned by valve that have 2 instances of the game. When subtracting 2 from 5 you get 3. Gaben made 3 all along we just never realized it. Oh and also we still need a couple of people to join the raffle if you want to be in it just put "yo" in the comments for the raffle announcement. But anyways Lord Gaben's secret about three has been discovered so please spread the truth across the land!!!!
