Since going on sale in March, 15,000 tickets have been sold for the Eurogamer Expo, and it’s half sold out. Last year, 20,000 folk attended the event, and additions this year include a dedicated MMO zone, and the Indie Games Arcade. It all takes place September 22 – 25 at Earls Court. Tickets can be purchased from the official site. Thanks, GI.biz.
