I built haunted houses for my game and also plan to have one as a business. Will have a ghost couple live in the home with haunted residential lot and own the business. They will scare customers, as well as have the usual haunted paranormal pack activity. Plan to have rooms available for those brave enough to sleep over. Maybe have medium tables in attic for classes for those who want to learn. Also planning to have an evil witch ghost to live in the conjuring house I built (the house in real life but made one from the movie as well). Should be challenging and fun to do!
