I already posted this to MeFi Projects, but it's relevant here I suppose, especially since one of the reasons @Play hasn't had a column for a couple of months is because I was working on this:
Game Design Essentials: 20 Non-Computer Games
There are certainly many more board games, card games, roleplaying games and others that I could do sequel article, and have been lightly planning one. Agricola and Acquire would probably be on the list because they're excellent and I have easy access to them, Dipomacy would be on the list because it's the most requested game in the comments to the first list, beyond that I'm still deciding.
Hopefully there'll be another @Play before DragonCon, maybe two. Watch this space.
