Impact: With virtually no marketing budget and a development team composed of a single programmer from Sweden, Minecraft has compiled an astounding 1.75 million sold copies and over 6 million user registrations (both as of April 1, 2011 according to Mojang) with cumulative gross revenues estimated between €20 and €30 million. On the Apple App store there are already dozens of Minecraft related guides and companion apps, including a $2.99 iPad/iPhone “World Explorer” that allows users to import saved Minecraft worlds from the PC game. The Minecraft’s user base already has a significant overlap with the iOS audience. Given the viral nature of game, and kid-friendly graphics and content, there is significant potential for Minecraft to become a breakout hit on the Apple platform. However, the game is significantly more complex than iOS sensation Angry Birds – and is likely to be priced higher – such that we don’t expect Minecraft to reach nearly the same unit sales level even if it becomes a major success compared to typical iOS games.
