I picked up a flyer for Supanova on the weekend. Last year I only went as an observer. I didn't run any games, but I took my nephew along and returned with a couple of pieces of Madman merchandise and several photos of some cosplay people. I can't imagine myself getting into that hobby, but I'm always impressed by good cosplay.
So this year I've promised to take my nephew again and we'll have a cool time, and I'm also thinking about returning at a separate time to check out some more goodies, maybe play a couple of demo games or just hunt for indie games fans.
