How about some NPCs or House guests you could QUEST to get? Maybe collect the bones of a long lost hero and allow them to rest in your home and having a ghost npc which you can set on a path thru out your home or property?
Also I UNDERSTAND there is a select group of people who would not want visitors etc etc..
BUT for those of us who would enjoy showing our homes off, how about a way to list our homes maybe in capital city's .
This would do the following.
Allow more for a sense of community
Encourage others to decorate their homes and show them off
Give people ideas on how they might want to decorate their homes.
Put youtubers who make videos of other peoples homes out of business. ( give them more time to play ESO instead of make YouTube videos)
Bragging rights for acquiring decorating items from quests thus encouraging others to try and obtain that item.
Its an over all WIN to give us the option to have some sort of listing that appears in game where people can randomly visit other peoples homes.
SWTOR did it and it was really fun, It would be nice to see ESO do the same thing.
