Except the best VR headset and the only good form of tracking in VR. TF2 is beyond ancient, CS:GO has over 600,000 concurrent players right now, and why should I care about whether they make games when they're backing the open system that allows anyone's VR games to be played on any headset? Facebook tried to make everything exclusive, and it was SteamVR that forced Facebook to compromise.
