Unless you’re one of the competitive gamers, the last two days of Blizzcon (in this case, Nov. 2 and 3) are all that really matter. That’s when the fandom crowds into the convention center, often in costume, to attend one of dozens of informational sessions. But this year, people were encouraged to start watching on Oct. 25, when the only thing to stream was the early stages of the Heroes of the Storm championship. If participants logged in and actually paid attention, Blizzard offered them a shot at tickets to the physical convention, discounts on goody bags, and 20 percent off all convention merchandise. The gamification continued into the convention’s peak as Blizzard announced new characters in Overwatch, and the launch of a Diablo mobile game. TK.
