So yeah, I really like the basic ideas behind using stats for a noble house as backdrop. But I think there's some flaws in the system. Specifically:
-Houses scale from 10-70 on resources, with linear increase in strength of holdings, while the curve should rather be exponential.
-Because of this influence and status often does not properly reflect the material holdings that these are based on.
To begin with, I'll nail down some definitions:
-Rank is where the house stands compared to others, where 0 is a peasant family and 70 is that of the mightiest great house. I'm leaving the King out of it, because the Iron Throne generally does not hold direct command over as many resources as say Highgarden or Casterly Rock.
-Resources is used to buy holdings, like current rules, and are derived according to the formula: Resources=Rank*Rank/10.
-Holdings as current, but with modified costs.
Note; I am not going to present a final product, not yet anyway, the separation of rank and resources could result in a fair bit of unbalance. And I'm mostly interested in getting my general ideas out at this point. The system will also most likely lead to that player created houses perhaps becomes slightly stronger. Don't get caught up too much in the specific numbers presented.
Change number one: Status and Influence.
The Influence resource is no longer used to buy status for heirs. It is used for buying house status:
Knightly House: 10, status 2
Petty Noble House: 40, status 2
Minor Noble House: 160, status 3
Major Noble House: 250, status 4
Great Noble House: 360, status 5*
*Requires the Iron Throne to approve. As there can only be one great house per realm. Though arguably, a "vassal house" might reach the status of being "great" if the paramount house also holds the title of warden (House Hightower probably is the closest to qualify as such).
House status works in the way that it determines what kind of status members may purchase. The Lord, his spouse, their children and their spouses can buy up to the listed amount. First cousins have the listed amount -1. Second cousins have the listed amount -2. Children of First cousins have the listed amount -2. And so on. Castellan, steward and master at arms has the listed amount -1, Sworn swords the listed amount -2. It will never go below 2.
With this comes amended benefits:
Landed Knight, requires Knightly House: +1D to all status tests.
Lord of House, requires noble House: +2D to all status tests.
Lady of House, requires noble House: +1D to all status tests.
Heir, requires noble House: +1D to all status tests.
Warden (of the North, south, east or west): +3D to all status tests.
Member of the Small Council: +3D to all status tests
Hand of the King, Regent: +4D to all status tests
You only get the highest bonus, and I'd generally advise that characters being appointed Hand of the King swaps out his lord benefit with hand of the king benefit, or whatever it is he has.
The Influence rank, in my opinion, should be have two components:
1. Base influence rank is the average value of your rank in defense, lands, power and wealth.*
2. The Influence modifier, which is a number between 0 and rank/5 which is either added or subtracted.**
*Without more in depth rules for Law and Population than a modifier on house fortunes, I don't really want to factor them in.
**This is what will be rolled during house creation, which will be influenced by events and realm. Probably, this will mean that you don't make the 7d6 roll for influence at all.
For expansion, I would suggest introducing "House Qualities" benefits which would cost rank*10 resources and drawbacks that would give rank*10 resources. For example:
All members of the House gets +1B on Status reputation.
All members of the House gets -1D on status reputation. (I imagine the Freys have taken this one).
This could maybe be done for other types of resources also.
While it would be fun, I'm not going to look into law/population, they have no holdings associated with them.
Changes to holdings:
Defense, here, resource inflation needs to have a corresponding increase in holding cost, so without much further ado:
Small Castle: 90
Large Castle: 250
Superior Castle: 360
Extraordinary Castle: 490
You could skip the latter two steps, but IMO, Harrenhaal is so much bigger than Winterfell that I think they should be there for the sake of completeness.
For Land Holdings, I wouldn't change much, the core idea of mine is that a house with 70 of something has a lot more than 7 times than a house with 10 of the same thing. A house of 70 of something has like 50 times as much now.
Except for communities, which I would increase in cost along the lines of what I did with castles above.
Power would be much the same, but with the add-on that the cost of a banner house is equal to it's power rank. A Banner House with 50 power (with banner houses and units worth 250 resources) costs 50 resources.
Wealth is the tricky part, you'll run out of options fairly quick, to mitigate this, you could increase prices, introduce more diverse holdings. Or maybe make it so that every holding you buy increases the cost of any further holdings. Say, the price of a new holding is increased by 1 for each wealth holding you already have.
