I don't know what you did for Tabletop Day last year, but I had a fantastic time going to my local game shop and playing games. Dragon's Den in Short Pump, VA is my store of choice, and they put on quite a game-filled day for last year's Tabletop Day.
I got to play Cthulhu Fluxx for the first time, and discovered that the rules for that variant of the Fluxx games are far more complicated than most. I also saw people enjoying wonderful games like Gloom, Sentinels of The Multiverse and Dixit, to name a few.
Here's an ad that Felicia Day and Wil Wheaton did to promote awareness of Tabletop Day on the USA Today website.
Take your family to your local game store and check out some new games. Tabletop games are all the rage right now, and there are tons of fun games out there. Your local game store owner will be happy to introduce you to them. You can also check out my link on the left for the full run of Tabletop episodes (Geek & Sundry's YouTube show), featuring wonderful games and how to play them.

To quote Wil Wheaton, "Play more games!"
