I bought it a few months back. Very fun, but the UI and general tutorial needs a lot of work as they are quite sparse. IMO.
As a new player I found it incredibly frustrating being left to figure out a bunch of stuff on my own. I ended up not playing it because I was struggling with stuff (like the waterwheels, and some other stuff, I forget) it really felt like a life commitment to just play DF.
It's a good game but BOY has it been tough to figure out.
