Bought that (the boxed copy, which unfortunately requires Steam), but haven’t played it yet. Since it is an episodic release, I’ll likely wait for the last part, likely spring 2018.
To be honest, I did not really plan to buy it, but seeing it while shopping I could not resist. Let’s call it my investment in Daedalic, so they’ll eventually get a grip and finish The Devil’s Men. Plus, it runs natively on Linux.
As for the game itself, I’ve yet to read anything by Ken Follett, though I don’t mind historical fiction in general. Means storywise there’s little to complain. The gameplay is said to be somewhat different than a classic P&C adventure, so my expectations are fairly low in that area.
