I actually want to piggyback off of @navy-spew‘s idea about the Winchester house. Because, while I know a lot of people in the clue crew complain about CUR and TRT being too confined to one place and they wish we were given more locations to explore, I actually think it’s a strength for the games. Mostly because that sense of claustrophobia is really good for psychological suspense. But the Winchester house would be like if both of those games had a child and that child was also raised by MHM. Because tldr version, house is big and haunted and has lots of weird things that lead to nowhere and there were lots of seances and shit there during Sarah Winchester’s life.
Sarah Winchester is in herself a mystery. Like aside from the little portrait her when she was young, this is the only photo we have of her (to my knowledge)
How fucking creepy is that? She was intensely reclusive. We also have no idea why she built the house the way she did (look into it it’s super fucking weird because it was meant to “confuse the spirits”) but the story goes that after the deaths of her infant daughter and husband she was so devastated and grief stricken she consulted a lot of spiritualists and mediums to try to get in touch with them/understand her loss. Because her husband was the son (?) of the guy who invented the Winchester rifle, one medium told her that she was basically being cursed and haunted by the ghosts of those who had been killed by the rifle and the only way to life the curse was to move, build a house, and never stop building. The good spirits supposedly would tell her what to build and if she didn’t then the bad spirits would haunt her forever and she would die. I think it’s got just the right amount of is it haunted? is it grief? is it something else? for the typical HeR take on a ghost game. They also keep finding strange new rooms? I think the mystery of the house, the hauntings, and the mystery of Sarah Winchester herself would be a really cool premise to base a mystery on.
