Board Games - You should be playing them. Also, April 30th is international tabletop day.

I used to play a lot of bookshelf games like
King maker, squad leader, victory in the pacific , diplomacy, civilization, just to name a few. I have them all packed away now. No longer know anyone that likes strategic games like these.
I have unpunched versions of Civilization and Kingmaker and Dune on my shelf right now -- I bought them to replace mine after Katrina (man I lost a lot of board games to Katrina) and haven't played one of them since relocating to Georgia. :( My bookshelf used to look like an Avalon Hill catalog.
