Sunless Sea offers a rich, text-heavy narrative experience that heavily engages critical thinking, strategic planning, and reading comprehension. Players must make difficult decisions with permanent consequences, fostering adaptive challenge and problem-solving skills. The game encourages creativity through customization and exploration, and deep learning transfer as players adapt to its unique mechanics and unforgiving world.

The roguelike nature of Sunless Sea, with its permanent death and potential loss of significant progress, could lead to frustration and a sense of escalating commitment for some players. While lacking direct monetization, the game's design encourages continuous play to mitigate the impact of failure. The dark, Lovecraftian themes and occasional descriptive violence may be unsettling for younger audiences, and the game's emphasis on solo play offers minimal social-emotional benefits.
