Regardless, the launcher passes through various parameters to ck2.exe to set which mods to load and which DLCs to exclude:įor example, this would theoretically launch the game with 2 mods enabled and 2 DLCs (Russian and Mediterranean Portraits) disabled: 'C:\Programs\Games\Steam\steamapps\common\Crusader Kings II\ck2.exe' -mod=mod/Realign_Celts_Men.mod -mod=mod/Edits.mod -exclude_dlc=dlc/dlc014.dlc -exclude_dlc=dlc/dlc016.dlc Launching the game via Steam -> Launcher -> Game appears to do some magic, aka it seems to trigger verification of DLC ownership that launching the game via just ck2game.exe -> Game or just ck2.exe does not.
