I've been working on my hardcore adventures, have a forest house, a castle to live in, some mining expeditions. Best of all it is all connected with tunnels, so I don't have to worry much about dying. I have this feeling back in my mind that I'm going to die from falling and like KabanaBoy said its going to feel like a big waste of time once that happens, but as of right now the mode brings a whole new challenge to the game.
