I am DYING for something more sci-fi or steampunk to play around with, hell maybe a fairy garden or wizard tower, a cave house or grotto under the sea, a thief's den, a superhero's headquarters or a villain's evil lair, a house hiding a time machine or a mad scientist's lair. Those things are only somewhat possible in the game right now, and it gets old messing around with normal style houses all the time, which is why the Halloween themes were a breath of fresh air in this game. Would require walls that can be built diagonal or round!
