This was the first time my costume changed over the three day convention, just as that poor bastard in the video shows his wear.
Glomping works a little like mass spin-the-bottle. Where your bottle points, you walk until you reach someone on the outer ring, hug each other, and trade places. They go to the center and find a bottle and you wait on the outside to get pointed at and hugged. This game is a lot of fun, and SonofV played it until they closed due to darkness and attrition (about midnight).
Another fun game is Cosplay Chess. On the left is black with a couple of Team Rocket pawns nearest the camera. The other characters are also well chosen re: good vs evil. When they come into the same square, they battle. I didn't get up to speed on all the rules, it was a little overwhelming.
