Have you ever noticed how courtiers of a dynasty, when not influenced by the player, tend to 'not' marry after some two generations or so of sitting on their hands as courtiers, and subsequently ending that particular branch of the family? Well, what if it's the way of the game representing that that particular branch pretty much became plebeians, and thus the records have been lost to history due to unimportance?
This goes hand in hand with the mechanic of inviting (read: creating new) nobles to your court. They didn't just form out of thin air. They were always around, but when invited they become a part of recorded history.
They seems to be a divergence between a character's physical traits relating to their appearance (specifically the "Attractive" and "Ugly" traits), until you realise that you are looking at their portraits. Portraitswhich can be embellished or vandalized.
This one is very sad, and very appropriate for the time period. Did you ever notice, out of all the marriages that are contracted throughout the time period, how few wives and husbands love each other?
Although most of the event chain leading up to that part involves the dominant of the pair to splurge and buy the most expensive item. Which is also just like in actual history.
The beginning of the War of the Five Kings can be explained using the game mechanism. When King Robert died, Stannis got a strong claim on the Iron Throne because he is the third in line and Renly got a weak claim. Stannis pushed his strong claim as the casus belli for rebellion. Because the title was in dispute, Renly could push his weak claim too. Robb Stark created an Independence faction, the Tullys joined this, then they revolted. Finally, Balon Greyjoy declared a prepared invasion to Robb Stark.
Likewise, Robert's Rebellion triggered from Aerys accumulating massive tyranny penalties for executing Rickard and Brandon Stark without an actual trial, leading to Robert, Jon, Ned, and Hoster forming a faction to press Robert's claim. Tywin eventually joined the rebellion by marrying his daughter Cersei to Robert, and his plot to kill Aerys triggered (with Jaime doing the deed) as the Starks and Lannisters were beseiging King's Landing. Viserys became the Targaryen king with Daenerys as his heir after Aerys and Aegon died, but the two of them were exiled to Pentos when the war ended.
And the way that the TV series ended also makes perfect sense from a CK perspective. The Stark dynasty swoops in after the repeated deaths of everyone else who would have claim to the Iron Throne, with a temporary council electing a monarch with the best stats in Learning, Diplomacy, and Stewardship. With another Stark in control of the independent North, it ends with all of Westeros under a single dynasty.
Sometimes in CKIII, your child can receive a four-star education in Intrigue but you getting the same message as them having a pathetic one-star result. This could just be Good Bad Bugs, but it makes pretty good sense that your child has mastered the art of intrigue so well that they know the power of pretending to be useless.
