Someone on the fringes might regard what Markus did as intellectual-property theft. Without beating around the bush, he revealed where he found his inspiration and even went as far as to call Minecraft a clone of an existing game. But game developers, more than other kinds of artists, often find their starting point in an existing idea that they then work on, change, and polish. … For most people, the colorful numbers and letters that filled the computer screen would be completely baffling, but Markus felt right at home.

The idea for Minecraft began to take shape in his encounter with Dwarf Fortress.
