Minecraft wiki entry for RubyDung, associated text: The game featured a 3D isometric perspective, as opposed to Dwarf Fortress's 2D tile-based graphics. It also included a 3d texture mapper, and randomly colored grass and cobblestone textures on the fly. The terrain generation was quite varied, containing many bumps, hills, and monoliths. Unlike the blocky nature of Minecraft, there appeared many sloped surfaces. There were trees using billboard sprites present in the game as well, of which there are lots of in the screenshots that they are present in. In earlier versions of the game, there was also a dirt material which formed maze-like dirt paths, and an alternate, earlier grass texture less resembling the one seen in Minecraft. The only known creatures implemented were the bunny and the hero. It is unknown if there were any sprites for them.[5]
