while i have in no way seen all of the new furniture items i haven't seen anything so far that is more than just decoration. If it hasn't already been done then here are a few ideas for pieces, let me know what ya think.
An arcade game machine that gives access to the mini games. A soda machine that lets you buy potion refills. A special wardrobe that allows you to color your outfits. A cage or kennel that allows ya to display one of your pets.
these are just a few things i came up with that could help make the housing usefull as well as cool to have. :-)
