AI really needs to de-prioritize marrying into family

[Xenrek]

So, finally got an immortal event chain to complete, yay.

Figured I should probably land a few sons around france just in case something bad happens to my ruler, there'll be living family as backups.

30 years later, all of my sons remain unmarried dukes except for the eldest who had been married by me before being landed.

10 years after that, most of my kids are going on 50, and *finally* are looking for marriage, except they only want to betrothe to my first son's daughters, the eldest of which is 8.

My whole dynasty is going to die out because they refuse to *not* I breed.

Can we like; get this fixed?

The AI seems fine for NOC dynasties, after 35-40 theyd often just pick a random courtier and get hitched. Just seems like the player's dynasty have massive alabama-syndrome for nieces and cousins

Prestige effects. As relatives to an emperor they are loath to marry lower than someone related to a king. They'll wait to their late 40s before they hold their nose and marry someone of lower standing. It's what typically messes with Karl in the Charlemagne start, ensuring Francia goes to hell if he doesn't live to his late 60s.

Incidentally your grandaughter is related to you, so there you go.

For me it seems even worse in enatic societies. Most of my vassal will marry their heiresses to some kinsman 15 years younger, ensuring dynasties dying out, since they also, at best refuse to marry off any back-up daughter. I have to personally intervene and offer lowborn consorts so their dynasty survives

Does this only happen for emperor relatives and not kings? I've been restarting a lot in 1066 Castille runs lately trying to get enough Reconquista participation for a bloodline, and it seems like Alfonso and Garcia often marry lowborn women despite being kings.

the absolut worse is when you Reform your pagan faith with devine marriage, I cant remember seeing a relativ not marrying its child, and this is realy frustrating because everytime a ruler loses his wife he rather bethroth himself with his only daughter child and thus will either die without a male heir or he will live long enough to make a inbred child with his daughter.
this is a vicious circle which lead to several family Branches who ruled hole kingdoms Go extinct. quite sad

all this is why I always force myself to Mikro all the unmarried familymembers.
I'd Love see a Change to this behaviour.

100% agree with the OP. One way around this is to land as many of your kids and kin inside your realm. Those dynasty members tend to be happy to marry their kids to each other. Of course, after 2-3 generations of this you end up with a boatload of inbred or weak dynasty members- which is dangerous if you are playing eldership, tanistry, or other elective succession.

It is also ridiculous how many AI rulers will marry their daughters in a patrilineal marriage, and lose their titles to another dynasty just to get a temporary prestige bump or a NAP.

speaking of marrying daughters, ive lost 3 enatic-reform games because of that :/ no matter how many dynasty members i land, theyll always wait until 40+ to marry because they only want to marry the youngest dynasty member they can find. but then thats just one of dozens of issues with succession/marriage in enatic realms not being weighted for the AI. that coupled with it being Open Succession means once you land a dynasty member, their titles will rarely split out, meaning quickly you end up with only a single, weak, inbred line of female dynasts who are all barely able to get 1 kid out after marrying at 35

I think it's because by the time you form an empire as a pagan your dynasty prestige is so high your AI relatives get biased and only marry within the dynasty.

This is a big problem in my game as well.
I'm playing a Byzantine Hellenic Empire ( i haven't choose divine marriage during reformation ) and almost everyone of my dynasty is marry someone into my own dynasty also in a complete crazy way. I have a kin queen into her 30 who's spamming to betrothal my 4 year old son for no reason at all, while there's plenty of landless kinsmen and kinswomen unmarried out there.
I manage to solve the problem of those landless kin by choosing their marriage but if they are landless that's more problematic.
