Minecraft recently reached 15 million in sales, according to a tweet from the game's creator, Markus "Notch" Persson. The game passed 14 million sold on PC in early February, and hit two other sales milestones on other platforms this month: 12 million copies on Xbox 360 and 21 million for the Pocket Edition on Android and iOS.
Minecraft first arrived in alpha form in May 2009, well before its full version release in November 2011. Developer Mojang recently launched the subscription-based Minecraft Realms service for hosting multiplayer worlds, which starts at $13 per month. It plans to launch a boxed retail version of the game on PS3 in May, which sold one million copies digitally in its first month on PSN, as well as PS4 and Vita versions in Q2 or Q3 this year. The upcoming Xbox One version of Minecraft will allow players to transfer their saved worlds from Xbox 360, just like the versions for the aforementioned Sony systems.
