The situation of this mod (with the English houses) lends itself, i believe, to more emphasis on the role of the princess and the marriage between factions. I read this in Dominion of the Sword:
Princess dowries Now when a princess is offered for marriage, politics are involved! If you want to marry off your princess into another faction you will have to pay for the honour. Depending on the size of your purse you will pay a varying amount to the host faction you are marrying into. This price varies with your treasury, but the poorer your faction is the more it will have to pay. This reflects the situation of small weaker factions having to financially 'convince' the man's faction that they are worthy enough. If you are receiving an offer of marriage from a princess, the greater your wealth the greater the dowry paid to you will be- again this reflects the respect that the princess's faction holds for the power of your faction.
I think it would be perfect for this mod and I reckon we should add a region to this, to signify the inheritance of the son. This would add so much politically to the mod, and would fit perfectly, especially between the English factions.
Let me know what you think,
Cheers
