I think that it would be neat if they offered massive packs of generic npc decorations with basic animations. For example an undead pack with 50 skeletons, 20 ghosts, 10 wraiths, 5 liches and so on. Or like an automaton pack or a bunch of animal and npc packs. I work on houses in eso for gold and I know that a ton of people would like to see scholars, students, and tavern people. Why not have wolves for your hircine? Or undead to guard your Wraithhome?
