Started when it was in Alpha because my brother in law said it was awesome. No one told me you could build tools and such, so I dug out (by hand) a fortress out the side of a mountain that was 7 floors where each floor was 3 blocks tall (technically 5 of you count the ceiling and floor). I showed him my achievement, both proud and frustrated. He asked how many pickaxes and shovels I went through, my response was something around “…what?”
