Every visual in Mundaun was hand-penciled by a single developer. You can feel that in every frame. The Swiss Alps setting is not a backdrop, it is the horror itself, a landscape of folklore and isolation that makes the mountain feel actively hostile before anything supernatural appears. I have a soft spot for horror that is grounded in a specific cultural mythology rather than generic darkness, and Mundaun has that in quantity. The game is slower than most entries on this list and the mechanics are rougher around the edges. It sits at ten for a reason. But as an auteur statement, as a piece of folklore horror that could not have come from any other source, it belongs here.
