In a blog on www.Mojang.com the deal was confirmed today with a few details about the sale and the reasons why.
The main reason Markus “Notch” Persson, the creator of Minecraft and the majority shareholder of Mojang has decided to sell is that he feels that Minecraft and Mojang have become to big on a global scale. He has attempted to make smaller games again to no avail and he feels that is because he has had to spend to much time and energy focused on the global phenomenon that is Minecraft.
There are only a handful of potential buyers with the resources to grow Minecraft and Mojang have worked closely with Microsoft since 2012. They have been impressed by their continued dedication to the game and its development.
The other versions of Minecraft will still continue to run but as for what happens with future multiplatform projects is yet to be seen. That will be down to Microsoft to decide.
The founders: Notch, Carl, and Jakob are leaving Mojang with nothing confirmed of what they are going on to do.
The main points to take from this sale is that Minecraft will continue to evolve and thrive and that small project you are working on may net you $2.5 Billion.
