I would love it if firendly NPCs came around to give me information on things like rare ores and treasures! Or NPCs in need of help in a form of a quest. I think I'd abuse the ability of NPCs to look for me in my house to kill me, unless they come through some other door/window other than the front door, which would be awesome! I guess a drink shared here and there wouldn't be too bad, but my Fire Mage loves to show off his Fire spells, and that never goes well.
real adventurers dont stay in their houses except to drop off trophies
I go to my house to drop off my loot, I can't fit my trophies in my house. Glarthir just won't fit in my bedroom display case, I just got annoyed and threw him in Eyja's bed in the basemant.
Man, that was one awesome Shepard Pie.
