Eh, Gaiaonline does it too. And I think Club Penguin, sort of.
But yah, I've pretty much never liked house features at all. I dunno. It just seems a little silly. xD I guess it's not too different from avatars, but.. the avatars are pretty well usable as personas or characters. Which a lot of us have. Houses are just kind of random - more a thing to show off your stuff than a personal customisable.
