I am trying to build a good world in hardcore mode and this is what I have come up with so far. The world spawned me in a Taiga right next to a desert. The base is a wooden cabin. I have a large tunnel system under the wooden cabin. There are large walls surrounding the wooden cabin as well as some chests with all my materials in them. There is an above ground tunnel system to the south of the cabin with two entrances, a connector to the tunnel system under the cabin, and two entrances to the wall surrounding the cabin as well as a snow farm. My newest addition to the world is a snow field (that I placed in the dessert for the irony) that is set up for capture the flag on a server. Please notify me if you have any ideas of what else to add to the world.
