Sunless Sea review
Wonderful writing resting on top of infirm foundations. Almost a classic, Sunless Sea falls a few leagues short of its final destination.

Sunless Sea is a brutal roguelike with amazing plots and writing that still hold up years later, but if you're looking to explore the Unterzee, the Switch port is not the way to go.
