Minecraft is much more than 'Lego online' - it's a creative classroom tool

When Markus Persson began to code Minecraft one weekend in 2009, he imagined a game without levels, story or points set in a vast, free virtual world, the future of which would be at the behest of its users. In doing so he created a gaming monster which, to date, has been downloaded more than 60 million times and is so popular that videos just discussing the game on YouTube attract 2.4 billion views.
