The Penny Arcade Expo is one of our favorite gaming events, hands down. The East Coast version of PAX won't launch until 2010, so you've got one more opportunity to make the pilgrimage to the original Seattle location. Lucky for you, registration opened today! You can pick up a three-day badge for just $50, and pre-registrants are also eligible to participate in the Omegathon gaming competition. The grand prize: all-expenses-paid trip to the Tokyo Game Show and, uh, other prizes. Plus, we'll be there!
