Microsoft has agreed to buy Mojang, the Swedish developer of the Minecraft PC and console game, for US$2.5 billion, the companies announced Monday.
The deal comes two weeks after Mojang released a version of its world-building game for Microsoft's Xbox One game console. A version for the PlayStation 4 came out a few days earlier.
Minecraft is the most popular online game on Xbox, while PC users have downloaded it 100 million times since its 2009 launch, according to Microsoft. It touted the loyalty of Minecraft players, saying that 90 percent of paid customers had signed in on the PC version within the last 12 months.
That loyalty may make the acquisition a rough ride, though. When rumors of the Mojang-Microsoft deal began circulating last week, some Minecraft fans reacted angrily, accusing the independent software developer of "selling out."
They recalled Mojang CEO Markus "Notch" Persson's response to Facebook's plans to acquire Oculus, the maker of a virtual reality headset for which Mojang was developing a version of Minecraft. Persson initially suspended development of Minecraft for the Oculus Rift, although he later posted a message to Twitter saying he was "officially over being upset about Facebook buying Oculus", raising hopes that development had restarted.
Mojang said that the decision to sell the company was down to Persson, the company's majority shareholder.
"He's decided that he doesnt want the responsibility of owning a company of such global significance. Over the past few years hes made attempts to work on smaller projects, but the pressure of owning Minecraft became too much for him to handle. The only option was to sell Mojang. Hell continue to do cool stuff though," wrote Mojang spokesman Owen Hill on the company's blog.
Indeed, Persson has devoted much of his time in recent weeks to a whimsical effort to reimplement the rendering engine of the 1990s first-person shooter Doom in Dart, looking only at the unofficial technical specification issued by Doom's developer and without reference to the original source code.
Persson and other Mojang founders will leave the company, Hill wrote, but Microsoft said the rest of the development team will join Microsoft Studios, the company's game division. It hopes to close the deal by the end of this year.
