I had the chance to play AW for the first time at PAX this year (also my first time at PAX), though you didn't run my game. I was there only on Sunday and got on line at 1:50 to get going at 2, but I was told there was no one to run it then. So my wife and I busied ourselves and came back at 3:50 as directed.
A gentlemen named Orion ended up running the game, if I recall his name correctly. It was apparently his first time doing so, but that didn't mar the experience at all. He seemed to have the jist of things, if not maybe the specifics. We played until the show ended, and cut it off. I'm saddened that I won't be able to continue that game, as I've been thinking about my character a lot the past two days. I would like to have seen him through his adventure. I was really happy with the quality of the character I was able to develop in such a short time frame.
It's funny to read your briefing, as our version of the setting ended up having a very different geography.
