Despite Rare promising amounts of content on a previously unprecedented scale for them, players claim they have failed to fully show the game's potential. One player even reached the famed Legendary Pirate status, which is not an easy task.
Rare promised slews of content when they announced Sea of Thieves on Microsoft's Xbox press conference on E3 2015-2016. Whether or not they succeeded at creating a new game for players to sink their teeth into for hours on end, we cannot say. What we do know is that a player has reached the status of Legendary Pirate, as was the original goal in the first place.
In order to reach the rank of Legendary Pirate, the player had to get max reputation with the game's three guilds, Gold Hoarders, Order of Souls, and Merchant Alliance. This was no easy task, as it took him many hours of game time to reach the rank, even asking his followers on Twitch to help him by farming treasure for him.
Some players were outraged at this tactic, and even started using #NotMyPirateLegend on the Sea of Thieves subreddit. The subreddit is filled with posts of people arguing whether or not he deserves the title because of his questionable decisions and actions in order to achieve the status.
Rare stated that the game provides just enough content for the players to achieve the rank of Legendary Pirate, and when they do, that's when the game really begins. Rare stated they have heard players' complaints and praises and are working on further tweaks and adding more content to the game.
Reaching the status of Legendary Pirate gives players access to a new sort of hub, the Tavern of Legends, where they can accept legendary quests. These legendary quests seem no different from the ordinary ones every player can get, apart from the increased difficulty.
Sea of Thieves launched on 20 March 2018 after a four year long development cycle. It is something Rare wanted to do for twenty years after their cancelled Project Dream game back in 1998.
