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.
A subtle one regarding Muslim polygyny. In-game mechanics encourage Muslim rulers to marry some women past child-bearing age (defined as 45), due to the dangers of having many sons who may become decadent, and the intrigue in the household with wives who may plot against the heir in order to have their sons become heir. Now, the verse most commonly referred to with the topic of polygyny is Verse 3 of Surah 4 (An-Nisa [Women]). A translation by Yusuf Ali goes: "If ye fear that ye shall not be able to deal justly with the orphans, Marry women of your choice, Two or three or four; but if ye fear that ye shall not be able to deal justly (with them), then only one, or (a captive) that your right hands possess, that will be more suitable, to prevent you from doing injustice." The verse was revealed (along with others) after the Battle of Uhud, in which many Muslim men were killed, leaving widows and orphans. Thus, many argue that the verse has been revealed “because of God’s concern for the welfare of women and orphans who were left without husbands and fathers who died fighting for the Prophet and for Islam. It is a verse about compassion towards women and their children; it is not about men or their sexuality.”
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.
Nomad rulers can destroy settlements in their lands by pillaging them, but this increases the chance of rebellion in those counties. That's because the people in the settlement do not want to be massacred, and are rising up in a desperate fight for their very survival. Indeed, once the last settlement in a county is fully destroyed, the culture of and religion followed by the majority of the county's population becomes that of the nomad ruler's, as his clan settles in.
Really, just playing Nomads in general. These will tend to be your bloodiest playthroughs, due to the ease of building a large army to conquer your neighbors and how quick your dungeons get filled with foreign captives.
