I meant to post an update yesterday for day one, but between all of the titles to play, t shirts to grab and board games to learn, I simply couldn't find the time!
Right now I am posting from the expo hall while in line for a free, and totally awesome, Shadow of the Colossus shirt! Within the hour I will be lining up to attend the dungeons and dragons panel, wherein Gabe and Tycho (of Penny Arcade fame), Wil Wheaton and others will be playing a session! Sounds very exciting to me.
Last night I was found to be on the second floor in a table top room with Jacki, playing Battle Star Galactica the board game with four total strangers.
PAX is magnificent.
