PAX Technica: looking back at Penny Arcade Expo 2007:
It's hard to pin down what exactly the Penny Arcade Expo is. The point isn't to sell anything, although you can buy a lot of games and gaming-related merchandise at the show. The point isn't to hype games that are coming out, although this year many developers and publishers were on hand to do just that. The point isn't to organize tournaments
Every year it sounds bigger and more exciting. Maybe I'll make it to next years event.
