I have played CK3 for some time but oh god they made mess with inheritance. I guess I have to wait for some patches or something but I really can't do that much micro management. Previously at least counties in your primary duchy would stay yours, but now your kids tear your whole realm apart like its no ones business. You can be most powerful man on Earth and in split second you play as one country Emperor. Like who thought its good idea to do it like this?!?!
