Clay tiled roods and paper doors and interior walls
I would like to see tiled roofs as we have clay in the game. shouldn't be too much of a stretch.
I would like a castle. even if it's a complete building and you can just assing guards to it.
Also interior walls some of the bandit hide outs have elaborate interiors and I would like to have the ability to do the same.
Also path edging like stones or bricks or wood ( I know this would hinder performance. ) but for design purposes it's needed.
