Well, I'm no minecraft expert, but I would recommend that you set a clear goal as to what exactly you are looking to accomplish. Saying a "sprawling castle" is a basic idea, but when you get down to building you'll need something more detailed, say for example, how many rooms you want it to have, just how big you want…

Folklore, although, to be fair, at least ONE of my friends also likes it, mostly because we played it together. It was a PS3 launch title and exclusive.

Anybody else noticed the clock started ticking backwards at some point?

I recently started watching Gargantia on the Verdurous Planet, and I'd say it's pretty good, haven't finished it yet though.
