People think of haunted houses because they want to think every abandoned house is haunted. But, really, I think the real danger of an abandoned house is the actual house itself. Has anyone ever thought to make a game where the house is falling apart and you are exploring in the wreckage? With the addition of possibly meeting other people (living, not ghosts) who would not be happy to see you. Then, lets not for get the animals: insects, rodents and birds in particular.
Or is it just easier to be afraid of something fictional, like a haunted house?
Having written all that… I’d love to play something like Ravenloft if I could play without needing a group of others and all that extra set up (dice, character sheets, kit, etc). Best of all would be seeing the map, with the layout of the house and then exploring to see each room in all the architectural details. You can skip the ghosts and monsters for me. I’d just like to see the house, even a fictional house.
