The core Crusader Kings II seems to work well. (I turned off the in-game steam access. The startup sequence is very slow -- but running in windowed mode and moving the window around speeds it up. Once the game is running all is well. It is a very heavy GPU user.)
The DLC I purchased is listed in the steam client when I right-click on Crusader Kings II and select 'View Downloadable Content". Also I can see the DLC files in /data/Steam_Library/steamapps/common/Crusader Kings II/DLC.
The problem is that the DLC does not work. At the start of a new game I can not choose Viking Age: The icon states that the Old Gods DLC is required -- but I have it. Also if I try to click on "ruler designer" at the start of a game, I am also told I need the DLC, again I have it.
I have tried uninstalling the game and re-installing: Same issue. How do I use DLC in Linux for Crusader Kings II? Is there some master DLC on/off switch?
