Following the example of Lobo, I thought I'd post info about a fun gaming convention happening this summer:
Origins Game Fair
June 12-16, 2013
Greater Columbus Convention Center
5 days of gaming for $55 early bird price, $65 regular.
Game types include, but are not limited to: Roleplaying (tabletop and LARP), board games, miniatures, card games (collectible and non), family games, art track, family track, kids programming, Amtgard, costume contest, guests of honor (TBA), and of course the dealers' room.
If you've ever been to GenCon, it's pretty much the same kind of con, just somewhat smaller (10,000+ attendees).
