Haunted houses all looking victorian or granny style or stereotypically spooky in other ways, so that when the haunt occurs it really is no surprise. I had hoped for more everyday houses with subtle hints at paranormal activity: a dorm, a motel, maybe a refurbished old factory with hidden rooms...
(Yes, it is easy to download a normal house/dorm/freighter and change the lot type to haunted. But the little hidden extras that hint at the place's history are not easy to place myself, because if I place them, I already know what they are and where they are hidden, so the joy of discovery is missing.)
