[Interest Check] I had an idea for a Weird short run game about a group of kids trapped in a spooky haunted house that is slowly stealing parts of them trying to escape before they fade away completely. Think 7th Guest meets Mystery Incorporated meets Betrayal at the House on the Hill. But with kids.
Basically a bunch of kids wake up in a haunted Edwardian mansion and have to try to figure out how to escape. Some ghosts are hostile and some are helpful but it can be hard to tell which ones to trust.
Some ghosts might ask for 'favors' and give a reward. But every time they make a bad choice or run afoul of the wrong ghost or get caught doing something they shouldn't, there's a price.
Rewards might be clues, new areas of the mansion, an item they had or will have in canon, etc. But when a price is exacted, that means a piece of them is taken away. Anything from a memory to an ability to an emotion or a sense or whatever. Player's choice really.
