Sea of Thieves is a pirate adventure game developed by Rare and released in 2018 for Xbox and Windows, where players crew ships, explore islands and hunt for treasure. Its upbeat orchestral score, full of shanty-inspired melodies, became closely tied to the game's sense of freedom and cooperative chaos. Short theme clips spread through gameplay videos, streams and edits as an instant signal for setting sail. It remains popular because it instantly evokes adventure, even for viewers who have never played the game.
