Valve has sophisticated DRM. While Valve rarely bans users for purely offline DLC unlocking (they usually revoke the game license), they can lock your entire Steam account. If you log into multiplayer with an unlocker active, the anti-tamper system (VAC or custom Paradox checks) will detect a hash mismatch. The result is often a permanent multiplayer ban for CK2, and in extreme cases, a community ban.

Because Paradox titles rely heavily on multiplayer compatibility, every patch usually downloads the assets for all DLCs—even the ones you haven't bought. You own the files for Legacy of Rome , The Old Gods , and Holy Fury . The only thing stopping you from playing them is a small, 2-kilobyte text file or Steam registry key that verifies your purchase.
