It seems a tad bit unnecessary, house decoration is such a insignificant part of the game. I'd rather see them put more time into the important things. Also, there will never be multiplayer especially for something so useless.
If I wanted to decorate a house I'd play The Sims or The Sims 2 or The Sims 3 or The Urbz.
So yeah, instead of spending time and resources on something so incredibly pointless it's better that they prioritize important aspects to improve.
Hell, in FO1,2 and T we didn't even have "homes".
Fallout is the story of the wastes, not a room. Not for me I'm afraid
Pretty much those. Since I always roleplay that wasteland wanderer character, and since that is pretty much what Fallout is, I never settle down with a room or a house. Sure, I'd like something like a "ownable" hideout, like a little shack on some cliff with a view over a valley, a good sniper location you know. But designing its interior, I mean, it's just a temporary place you sleep at, store stuff and wait out a storm. It's not like your "Environment motive"-bar in The Sims needs to be filled or whatever.
