RubyDung

RubyDung was a building 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 randomly colored. It includes a 3D texture mapper made fully by Notch.

Notch included a first person view for following your minions around. 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.

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.

Creation of Minecraft
Soon, Notch played Infiniminer. He found out that this is the game he wanted to create. After some time, Notch created Minecraft, which soon gained popularity.

Minecraft' s source code came from RubyDung, so early versions of Minecraft have the rd (RubyDung) prefix. Early Minecraft versions were based on a combination of Infiniminer, Dungeon Keeper and Rubydung's source code.
