I hope they take note of the custom houses that the mods bring. Players (or at least, players like myself) want a place where they can take stuff with personal meaning to them and put it on display.
I'll give you an example. I use a gun 1/2 through my entire playthrough, and I am very attached to that gun. Or maybe it's outfit that I wore. In either case, eventually I'm going to find something better. In vanilla Fallout 3, I had a dresser FULL of old guns and another dresser packed with old outfits or unique items. I never get to see them... they're just lines of text in a box. There's this sentimentality about these items where shoving them in a drawer (or worse, selling them) that makes it just sad. Meanwhile, mods bring these houses with display cases and mannequins and it's just shows my evolution as a player when I'm strolling through between missions and I see my old gear. It's nice.
Of course, there's a lot of other things, (one house has an inground swimming pool! yay) but that seemed to resonate with me for some reason.
