Themed decorations is important if users want to build specialised rooms. By themed decorations, I mean items that you can craft that can be displayed in rooms and give the room a bit of variety and uniqueness that other rooms don't have. This could include paintings, wallpaper designs or even furniture such as plant pots. This can even link to the NPCs: - A bed for a room with the medic in. - A pile of gunpowder for a room with the demolitionist inside. - An assortment of items on shelves for a room with the merchant in. You get the idea, these should be in the background as they are decorations. This will add a bit more creativity within the game so that rooms are unique.
