Well, I have an idea.
INFLUENCE
Simply said, the more fiefs your faction control, the higher influence you have. This is just an idea, so don't take any of the formulas/numbers as final.
First off, three types of influence:
Village influence
The more village influence your faction has, the more goods you can craft per day in all your fiefs.
1 village = 100 influence value
Since we don't want to give advantage to big sized clans this way, the total village influence is divided by the number of faction members.
For example: we have 5 villages which gives us 500 influence value and 40 members in our faction, thus we have a total village influence of 12.5.
This would, as a result, increase the chance to make a village good by 12.5%. If you already have a 100% chance, this means that you would have 12.5% chance to make another village good.
Castle influence
The more castle influence your faction has, the more troops you can recruit per day in all your castles.
As for calculation, use the same example as the village one.
Town influence
The more town influence your faction has, the bigger the trade distance bonus in all your towns (or perhaps even surrounding villages).
As for calculation, use the same example as the village one.
Possible problems that would need to be handled:
- faction leaving/joining/hopping to decrease size/improve total influence
