RubyDung

RubyDung was a game created by Notch before Minecraft at an unknown date. Not much else is known about the game other than it is influenced by Dwarf Fortress.

About
The grass and cobblestone block textures that were used in this game were later used in Minecraft, and the textures were colored with a random color. He implemented trees which are not like the trees in Minecraft. Notch said on his blog that when he tested the game everything became heavily pixelated in which is the one of the main reasons why he stopped working on RubyDung. It was one of Notch's inspirations to create a block-styled game, which later turned into Minecraft. Despite not actually being RubyDung, early pre-classic versions of Minecraft were referred to as "RubyDung" internally, before Minecraft had a proper name.

RubyDung inspired Notch to make Minecraft when he wanted RubyDung to have a first person view, but when he tried making this, he thought that the textures were too blurry and distorted. Shortly after Notch's days coding for RubyDung, he came across the game Infiniminer, which put down the foundations for Minecraft.

On October 30, 2009, Notch talked about RubyDung on his blog in an entry entitled The Origins of Minecraft.
