Abzu (undersea exploration, relatively chill, but I never completed it)
@troyunrau Abzu isn’t an RPG, but I’d still second this recommendation, as it’s very chill to play, has zero combat, and has a lovely story to it. Would also recommend Spirit of the North for the same reason. No dialogue in either, though - the story is very much in the visuals, music, and atmosphere rather than words.
