Minecraft's runaway success caught many off-guard, none more so than Markus "Notch" Persson, creator of the game. Millions of copies later, he founded Mojang, and a new documentary focuses on the challenges of running a video game company. Minecraft: The Story of Mojang is a feature-length documentary that looks at Persson's rise to fame, and offers a detailed look at his new studio.
