Then one of the Valve staff walks by and asks us if we need help or if we're waiting on someone and we explain we're waiting on Chet. In short order we're greeted by another Valve staff member, Chet had been tied up in a meeting. I'm going to go ahead and say it was Erik that gave us the tour, even though that might not be right. Valve takes up the entire 10th floor, part of the 11th and 9th and a few offices on the 8th. We were only touring the 10th and part of the 9th, we were told that there's another "game design group" on the 11th; but details were purposefully vague. I think that Valve is working on a new project or it's Episode 3 in progress.
It's right about here that I think I should mention that Valve never asked us to sign a Non-Disclosure Agreement we get to write about everything we have seen. We were also allowed to take pictures just about everywhere, although I was so busy asking questions and getting answers that I didn't take all that many pictures."
