Classic Console and Arcade Game Show (CCAG)
Details
Every year I forget about this event, but not this year! And I will have spending money on hand to buy one of those hybrid NES/SNES consoles. :)
From Chris Sanyk about last year's event:
I've been going to CCAG show since I first found out about it, in 2005. Every time I go, I always see something I have never seen before, or never heard of before. If you like old games, this is your nerdvana. See, swap, buy, play everything from Vectrex and Odyssey to Xbox. Contests, auctions, prizes.
Admission to the show is just $5.
