SEATTLE - The Penny Arcade Expo is in full swing in downtown Seattle.
The fan-centric celebration of gaming began Friday at the Washington State Convention Center. The four-day long event is expected to be attended by 85,000 gamers and will include concerts, game tournaments, freebies and previews of upcoming titles. Tickets to this year's 10th annual PAX Prime event sold out less than two hours in May.
The inaugural PAX, named after founders Jerry Holkins and Mike Krahulik's "Penny Arcade" online comic series, was first held in 2004 in Bellevue, Washington, and attended by about 3,300 fans.
