I decided I'd like to change that for CK3.įrom what I understand, if I want to seize another kingdom and integrate it into my own via marriage-inheritance, say for example, playing as Aragon and aiming to get Castille, I need to ensure that the Castillians end up with an heir of my dynasty, and that that heir is simultaneously my primary heir. Between holy wars, the various special CBs of non-Christians, claim fabrication and extra options added by mods, it was not hard to dodge. Confession time: Despite having almost 1000 hours in CK2, I had maybe one run where the marriage-inheritance way of gaining new titles meaingfully came into play.
