Valve has sold all of about 10,000 tickets for its 2014 Dota 2 International Championship, the company has confirmed. “Tickets were gone roughly one hour after they went on sale”, Valve’s Doug Lombardi told Rod “Slasher” Breslau at GameSpot sister site onGamers. Tickets are already popping up on eBay for as much as $500. Key Arena could not confirm if another wave of tickets would be put on sale.
