Persson left Mojang in November of that year, selling his company to Microsoft for a reported US$2.5 billion. In September 2014, Persson announced on his personal website that he had concluded he '', that he had 'become a symbol', and that he did not wish to be responsible for Mojang's increasingly large operation. After this point, Persson stood down as lead designer and transferred creative authority to Jens Bergensten. Prior to the game's official retail release in 2011, it had sold over ten million copies.
