Or when you're Gabe Newell, and you get in a right old flap following an unexpected question about Counter-Strike 2. At GDC. On video.
Watch this and tell me if it's the action of a man who is unquestionably not making a Counter-Strike game in secret at his company called Valve.
It's not, is it? I mean it's not just me. Good old Gabe is flapping around like a schoolgirl who's just been caught with a boy's phone number, isn't he? Someone should have followed up with "Episode Three" while he was off-guard.
Reckon this points towards Counter-Strike 2 in the near-ish future? And if so, what do you want from it, given the insane degree to which Valve has evolved Team Fortress with TF2?
