Some people are really good at manipulating wizards. As the makers of a game that features wizards (also: bears, succubi, venomous man-reptiles), every year Valve invite some of these people to a multi-million dollar wizard-off. That tournament is Dota 2's The International, and is one of the year's largest e-sports events. Valve have confirmed that this year's tournament will run from July 18 - 21, with tickets going on sale later this week. In addition, the event takes place in a new venue: Seattle's KeyArena.
