Maybe also make the maintenance cost .....

I really like the idea of a maintenance cost for castles and it's realistic as well. Another idea would be placing some adjustment margin for the weekly maintenance cost where paying a higher maintenance would give troops better morale. For example- a well furnished room, with excellent food and services would do much better for morale then a cold floor, blanket with bread and water.
High Maintenance cost = 5 gold per turn
Average Maintenance cost = 3 gold per turn
Low Maintenance cost = 1 gold per turn

Oversway also has an excellent suggestion.
