The modding scene for Crusader Kings III is still very much in its early days—we’re a while off from seeing Westeros, for example— but fans are still coming up with cool little tweaks and additions.
The best one I’ve seen so far is Tony Hawk’s Pro Crusaders 1+2, which adds skating as a lifestyle trait. “Start skating” lets you skate to lose stress and adds a bunch of skating-related events.
Oh, and also “Genghis Khan spawns as a Skate Legend”.
You can get the mod here.
