I have started a 'Countdown to Gen Con' page on facebook. To bridge that gap for those who can't wait.
Every day, I plan to release a 'Countdown to Gen Con' card game card.

So far for the intro, now the on-topic bit:

The Order of the Stick makes the first Countdown to Gen Con card : #100 (we are counting down to 0).

To see the card, and to like, dislike, comment, or otherwise participate, visit :
