Microsoft announced its blockbuster $2.5 billion deal on Monday to acquire Mojang, the company behind Minecraft. In the five years since launching, the popular open-world game has racked up more than 50 million downloads and is available on multiple mobile platforms, computer systems and game consoles. An official release from Mojang says that the Minecraft’s founder, Notch, is moving on other, unrelated projects but most of the current team will stay on. Microsoft will surely bring the game to its Windows Phone handsets — or is that Windows handsets? — as Minecraft is already available for iOS and Android.
