It's a strange day when a YouTube star named CaptainSparklez gets bigger billing in a headline than the co-founder of Activision, but here we are.

YouTube phenom CaptainSparklez, whose real name is Jordan Maron, has partnered with Activision co-founder Howard Marks to develop Fortress Fury, a competitive mobile game. Maron and Marks operate at seemingly opposite ends of the video game industry, but working together, they've found common ground and cultivated more than 1 million downloads of Fortress Fury in its first few weeks on iOS and Android. In a video interview, the unlikely duo tell us how they first met (Grandmother Sparklez makes an appearance), and how the industry is evolving with crowdfunding, YouTube and eSports.
