The Washington show was just like the Dallas show -- a kind of sad offering of a few consoles and maybe 3 vendors. (One selling parody DVDs, one showing the Flashbacks but not selling them that I can see, and someone selling action figures.) No coinops and a slim selection of games.
I have to say, I was VERY disappointed. I've read reports on Philly Classics in the past, and when I heard they were coming to my town, I got really excited -- I can't go the PC because it's too far but having the PC come to me was a dream come true. All I got out of it was four wasted hours of subway travel and loitering. The press released mentioned lots of things that simply were not there / didn't happen. Feels like a cheap bait and switch.
