As promised, I recreated World of Minecraft. Obviously, this is not the tree city from the one I already uploaded, but I will somehow transfer it to this map save. The map save may be released when Minecraft is officially released, but if there are seed generator changes (such as Ravines and Rivers) I will start over to get the features.
One of the Uncle Scrooge comic books inspired me to build Lava Dam. I can't remember which one it was though.
