Minecraft Classic

Minecraft Classic is just like when Minecraft first came out a few years ago. There are no mobs, only one type of tree, and grass is a different color. It is no longer being worked on. And the world stops at a certain point (Left side of photo below), but it is still quite similar to Minecraft today. Minecraft Classic is free to play.
