Last month, all the three day tickets for PAX Prime 2010 sold out. Now the official Penny Arcade Expo web site has posted word that all of the one day tickets for the Seattle game event next weekend are gone as well. So if you think you can just show up at the door of the Washington State Trade and Convention Center hoping to buy event a one day ticket, you can pretty much stay home.

Last's year's PAX Prime event also sold out a few days beforehand and managed to bring in 60,750 attendees. However this year's event could see a large increase in attendees due to the fact that the main theater for the show has been moved to a location a few minutes walk from the convention center. That means there's more exhibit hall space which means more people can now be allowed to attend.
