Sandcastle!

I do hardcore.. one death and its over.  I once played a map for a month and had a fortress carved into the side of a mountain.  A minecart would whisk me through the valley and into a redstone-activated hidden door to a beautiful beach house and harbor.  Then it continued under the ocean to a glass-enclosed mansion on the seafloor.  A lava lighthouse, an offshore livestock farm.. it was a masterpiece.  Then one night while building a giant monster-spawning mechanism, a slew of zombies fell on me and I died.  Automatic delete.

Some people have way, way, way too much time on their hands. Yes, I used triple “ways” there.
