ToME WikiFor houses, maybe you could have larger houses in cities, and smaller ones in villages. You could also purchase additions with costs (and restrictions) similar to the house. Like in Minas Anor, after getting the house via the quest, you could purchase an addition for 50,000 au, and get a decent amount of space, while in Bree and addition would cost 20,000 au, and not get as much more space.
Also, houses could be like a dungeon, with your items laying on the ground and a space for a bed which you go to and use to sleep. Also, items wouldn't pile up, but like items would still stack (a stack of potions of Healing for example, but no items underneath it).
Maybe some sort of pen for pets in country towns, so if you dont want to keep your pet with you, you dont have to, but thats another idea for another page.
