I have been trying to understand why Microsoft would buy Minecraft. Even though Minecraft is really important, and wildly successful, but the price tag for a game studio with one successful game is rather odd, considering it is unlikely Minecraft will sell millions of copies more (it is already the most sold game ever made). This is a long shot, but it may explain it:<p>If Microsoft is trying to build its own Steam competitor (which given Valve's current strategy to make Linux an alternative gaming platform to Windows, makes sense), then Minecraft is the perfect acquisition to start it up, for a number of reasons. It is the best selling video game of all time, with over 15 million copies sold for the PC (54 million copies across all platforms), and it has over 100 million accounts registered. It is possibly the only successful indie game that has never integrated with Steam, and that has a very young userbase (based on my experience) which, given their ages, probably isn't part of Steam's userbase. All of these aspects make it a great strategic acquisition if Microsoft wants to make a new and successful game marketplace and platform for Windows.<p>Anyone else has any other idea why the 2.5 billion price tag?
