Sunless Sea mentioned! Most of its value is in setting, writing and atmosphere, which are all really well executed. The gameplay was fun enough, but combat is tedious and I tried to avoid it, like you’d do in a horror game. I see it more as a visual novel with some exploration and resource management. Focus on the story, the characters, the locations. Fetch a macguffin only because it makes the story progress or because it makes you go beyond the explored world, not because you’re so interested in the act of fetching.
