Mechanical benefit to decor items
It would be nice for more insentives to have decorated castles other than the looks. I would not feel like i am "wasting" resources if there was some mechanical benifit. Lets say a castle room or hallway gets a "buff aura" if there is enough decoration points in there or something. Sure, powergamers could still disregard aesthetics if they'd like, but i think it would make most of us feel it would be much more worth it to make immersive, well decorated castles.
