I've always disliked the 'furnishing' aspect of home owning in Fable. Especially in Fable II and III. There's barely any customization available. You just buy the highest 'quality' of furniture and auto-furnish the house to raise its value. Even if you don't do that, all the furnishings basically look the same except with some slight texture swaps.
I guess it doesn't really matter when the players best possible 'house' is a freakin' castle, but some genuine decoration options might have been nice.
