I think the new houses are a little meh. Sure you can choose your furnishings for them, but in terms of beauty and space (plus cool nooks and crannies) they don't hold a candle to my current Bog house!
Speaking of candles how custom will we be able to make them? Could we conceivably remake a Bog house including herb garden, barnacles and fireflies? What about the cool fossils and artwork on the walls, etc.? Could we go complete custom by designing our own artwork for furnishings, wall coverings, and the like? For me the amount of customization is only a half step to what I'd like to see.
We haven't even moved and already I'm missing my sweet Bog house...
