I recently watched an interview of Bill Tiller and somebody mentioned he owns Haunted Mansion Game (1972).
Looking this up led me to a much more recent board game: Scooby-Doo: Escape from the Haunted Mansion (2020).
It’s basically Maniac Mansion / SCUMM!
- You have multiple rooms.
- You collect inventory items.
- You can use those items on objects in the rooms.
- There are multiple characters (it’s a co-op game).
- You have multiple verbs (each character has its own, e.g. Scooby-Doo can smell, Velma can research etc.).
(I’ve learned this from watching this video: How to Play video by Tantrum House)
