One of the games I return to regularly is Crusader Kings 2, and usually, what pokes me back into its torrid embrace is a trip abroad. I ll go to a place I ve not really thought about much, then get well into its history and, because my curiosity writes cheques my attention span can t cash, I ll fail to read up on it at all. What I will do, however, is open palm slam good ol CK2 into the VHS slot on my computer, and play the shit out of whatever bit of history I m intellectually horny for.
