Perhaps some of the most gaming I've done in years. We started playing at 3pm on Friday and we didn't let up until Monday morning at 2am.
In no particular order, we played
Tomb (four times)
History of the World
Apples to apples
Wits and Wagers
Wayne's new game design
and a few other little games that I can't recall
While it's not good for the convention when attendance is down, I prefer not having to arm wrestle to find an open table.
