How 'Fortnite,' a 'Gamer's Game,' Took Over the World

Fortnite, a free-to-play shooter by Epic Games (Gears of War), has taken over the world. That may sound like exaggeration, but I couldn't overstate the popularity of Fortnite if I tried. It is massively played, and even more massively watched--on Twitch, 66 million hours of Fortnite have been watched in the past two weeks, with about 200,000 viewers tuning in at any given time. It is also, somehow, massively complicated. Fortnite started off as something less than a success.
