Markus Persson had worked for King for over four years until 2009, when he began full-time development on Minecraft. His idea brewed from a game he was developing titled "RubyDung", an isometric base-building game, and from Markus seeing Infiniminer, a block-based mining game and I will say office note Minecraft is almost the best game, but there's other game. It's perfect for kids and all ages.
