Here are a few suggestions about the French characers:
1) Raoul de Valois -if he is Raoul the Valiant as I suspected- should be renamed as Raoul de Vermandois, as he was the count of both and more, but known as the count of Vermandois. He also should be considered a family member, since he is the son of Hugh de Vermandois, and he is the cousin of the current king, Louis. If this character is who I think he is, he should also get a bravery trait, because he was known as Raoul the Valiant.
2) House of Blois should be removed from the family member status because they aren't related to the Capetians. The closest relation I could find was Thibaut de Blois' niece was married to Raoul of Vermandois, couis of the king- until their divorce and subsequent war between the Houses of Blois and Capet. At this point in the game, they are family members but they don't show up in the family member tree because they are NOT. They still use up space and because Thibaut has his own children, the royal House of Capet gets less children. This is caused by the game engine as explained in the game. They just leech off space and all of their offspring have the trait "father was treacherous" which drastically inreases the unrest in any settlement they govern, because Thibaut just can't be satisfied with the County of Troyes and wait to die.
This brings me to another point about the rebellious House of Blois. I don't understand why they are part of the French Kingdom. Thibaut de Blois should be a rebel general with a moderate garrison in Troyes. It is both more historical and practical, as he rebels against both Louis VI (current king) and Louis VII. He is always conspiring when he isn't downright hostile, and he supports his broher Stephan de Blois(soon to be King of England in the game) when France goes to war against England.
I could talk on and on about the rebellious, decieving rascals that is House of Blois, who tries to gain power in every opportunity not just in France but in Englad too, like the slithering snakes they are.
Ok, enough about de Blois.
3) Actually, no. I have one more argument about the character I most hate in this game. Even if you let Troyes rebel, because Thibaut is building his own empire there, he dies if the city revolts because he has -200 movement points and therefore can't even get kicked out of the settlement. The guy can't even get what he wants... He doesn't pose a threat to anyone because you can just lower the taxes and keep a few milita in there to keep him at bay, or just remove him completely from the settlement and wait for him to rebel alone, only to crush his skull housing his little plotting brain. He makes no sense from RPG point of view because he can't even rebel and take the city for himself, and no sense from normal gameplay POV because it is so easy to deal with him. It is just a really bothering waste of time, waiting him to die while rejecting every single marriage offer to his sons.
4) I don't know why Louis the Fat fears the English, as he went into conflict with them and not just sit in Paris like a coward. The most possible reason is the Battle of Bremule, which French disastrously lost, and the king himself lost his horse and banner to the enemy, escaping only with his life. This event didn't stop the French king from taking to the field however, so I don't think he was "afraid". Maybe I have missed something. Also Louis may start the game with a "grief stricken" trait, since he lost his firstborn Philip of France at the age of 15, and this event apparently devastated him.
5) Fleury Capet was married to Alice de Nanges and had a daughter named Elisabeth de Nanges before he died, so maybe a princess of royal blood could be added if found necessary.
6)As I've mentioned in my posts above, Philipe Capet shouldn't be the heir, since Louis would never make him one. Increasing the age of Louis' son Philipe by a couple of years and making him an actual character instead of a child, this problem can be fixed.
7) During the struggle between England and France to put an ally count on the seat of Flanders, Guillame de Nevers -our friendly, old, crusader, noble general- convinced Louis to back a guy against the English candidate. That is how the conflisct began. Because of this action, Guillame was imprisoned by certain somebody, can you guess who it was? Yes it is Thibaut obviously.
I have failed to find any good replacements for the characters I suggested to remove. Any advice would be aprreciated.
I've forgoten to cite my sources. Main source I used was the p. 637-659 of
Cambridge Medieval History Volume V. I also used some less dependable sources like Wikipedia, etc.
If a mod can merge this post to the other, that'd be great.
