At present, the mod contains a plethora of content for the main continent of the Rome-like Aversaria, with future updates promising additional content for Sarradon, the Middle East-inspired continent in the setting's south.
The most recent major total conversion mod to release, Godherja: The Dying World, is an enormous conversion mod replete with systems such as magic, dueling, artifacts, and coronations, set in an original dark fantasy setting with an emphasis on personal character narratives that play out through events and decisions. While the most downloaded mods on Crusader Kings 3 Steam Workshop tend to be quality of life changes or small content additions, the most celebrated among them are the total conversion mods, which overhaul the traditional feudal setting of Crusader Kings 3 into all manner of different settings, be they medieval Japan, the Bronze Age Near East or a vampire-infested Europe. When it comes to modding, Paradox Interactive made sure that Crusader Kings 3 would be as accessible and as customizable as possible for anyone wishing to add anything from as simple to a GUI update to as complex as an entirely new map. Some modders who had made notable contributions to Crusader Kings 2 were even given access to Crusader Kings 3 so they could get their mods out on the day of release.
