The description on the official site read: "The Sims Medieval Pirates & Nobles Adventure Pack introduces new quests, treasure hunting, and hundreds of new objects for your medieval kingdom! Your epic story starts when the Pirates of Aarbyville and the Nobles of Tredony arrive in your kingdom, followed quickly by sword fights, love affairs, grand adventures and mysteries. Go treasure hunting to uncover hidden objects. Embark on new quests to help your kingdom achieve a new ambition. Stylize your kingdom and Sims with new pirate and nobility themed objects and wardrobe. The fun never ends with this new adventure pack!"
On Origin as well as in-game, it is titled as The Sims Medieval: Pirates and Nobles although the EA.com website titles it as The Sims Medieval Pirates and Nobles without the colon (:).
Interestingly, the name of Pirates & Nobles is different from other EPs and SPs as it has a colon. The other game to use a colon is The Urbz: Sims in the City.
Despite the base game being available, The Sims Medieval: Pirates and Nobles is not available for purchase via Steam. This is a similar case to The Sims 3: Katy Perry's Sweet Treats not being available despite every other stuff pack, expansion pack and the base game being downloadable via Steam. Sweet Treats was later released during the Thanksgiving Sale along with previous expansions of the series but Pirates and Nobles remained removed from the listing.
