Player Affinity writes: The Penny Arcade Expo takes place twice yearly, in Seattle (PAX Prime) and Boston (PAX East). It's a celebration of all things nerdy; video games are predominant, but PAX also caters to tabletop gamets, roleplayers, fans of the Penny Arcade webcomic and nerdcore music aficionados. In the words of Jerry "Tycho" Holkins, one of the founders of Penny Arcade, it's the convention that he and his creative partner Mike "Gabe" Krahulik always wanted to go to. I was able to get hands-on with a couple of games over at PAX this weekend. One of those was Mass Effect 3.
