How Call of Duty developer moved from studio chief to a fan

Mark Rubin worked on Call of Duty games for nearly a decade. He was executive producer at Infinity Ward, the creator of games like Call of Duty: Ghosts, until early 2015. After he left, he experienced that surreal feeling of shifting from being the head of a 260-person game studio to being a fan.

He suddenly went from having no time to play games to playing games all the way through to completion. Rubin is still a heavy-duty gamer, playing games like Marvel Heroes 2016 and spending a lot of money in the free-to-play online game. In fact, he proved to be such a good fan that David Dohrmann, the CEO of developer Gazillion, invited Rubin to join the company’s board of directors.
