In a possible oversight, EA may have prematurely disclosed The Sims 4's upcoming DLC, confirming a pack that fans have been eagerly requesting for months. Since its inception in the year 2000, The Sims series has consistently introduced new expansion sets, ranging from realistic scenarios to more fantastical genres such as horror with The Sims 4's Paranormal Stuff pack or the vampire-themed Nightlife expansion for The Sims 2.

In May 2023, EA engaged The Sims 4 players in a vote between two genre-driven expansion packs: a fantasy-themed Medieval Castle or a High Tech Futurism pack focused on building. The Medieval Castle pack emerged victorious, sparking anticipation among fans. However, after the announcement of the results, EA remained silent, leaving the community eager for updates. Finally, eight months later, an inadvertent leak on the EA app provided the much-awaited information. As highlighted by Sims Community (reported via The Gamer), the UK version of the EA app revealed the "Castle Estate Kit" listing. The listing included two screenshots showcasing majestic castles built with the new kit, featuring iconic Sims characters, Bella and Mortimer Goth, conversing on a balcony overlooking the grounds.

Priced at £4.99, or £4.49 for EA Play subscribers, the Castle Estate Kit aligns with the typical cost structure for The Sims 4's kits and packs of similar size. However, it's worth noting that the listed release date of October 15, 2099, is likely a placeholder or contains an error, projecting a date over 75 years into the future.
