The Penny Arcade Expo, now in its fourth year, is unlike any other gaming convention. There's a different vibe, less glamour than E3 but more swagger than GenCon. It's a three-day party, and this year it took over the Washington State Convention Center in downtown Seattle. Uber-geeks, Utilikilts, untold silliness, and games. Lots and lots of games, of all shapes and sizes.
