Wildsea takes my favourite trope (non-water oceans), and sets it in a massive jungle, your cast builds their character as well as their ship, massive hulking machines made to cut through branches and leaves, and keep the sailors protected from dangerous radiation. Fire is rare, nearly non-existent due to its inherent danger, just a spark could destroy entire settlements, culture is varied, people are strange, and the sea is evershifting, after all, trees grow, branches change layouts, things change.
Overall, Wildsea should be checked out, its a fun time!
