The Sims 4 continues to grow, but according to rumors, this won’t last much longer.

The title of the 21st expansion pack has been officially revealed to be Royalty & Legacy, confirming all the rumors surrounding the final Sims 4 expansion pack. The official title of the final expansion pack will be The Sims 4: Royalty & Legacy. After that, we will supposedly get The Sims Project X, a new single-player experience. The alleged trailer for Project X has already been leaked. The title of the expansion pack was found on the official South Korean game rating site. It reveals the long-rumored theme of the 21st expansion pack in the series.

The listing only states the following about the expansion pack: “The Sims 4’s 21st expansion pack allows players to become nobles and build a long-lasting dynasty.” That’s it. Until now, speculation had circulated that the theme of the next expansion pack would be the royal family. This listing confirms it, as the information comes from the South Korean official game rating board. The name of the expansion was submitted on December 18, and the decision date was December 26. This leaked information coincides with an official Sims 4 survey conducted in October, in which players were asked to share their opinions on Legacy Play, Heritage, and more.

According to Twitter user @lunar_britney, the Royalty & Legacy expansion pack will be released in February. Regarding the expansion’s features, an insider rumor suggests that the next Sims 4 expansion pack will include a new world with three types of royalty. One of the areas or neighborhoods will be based on Africa. What we know for sure is that Electronic Arts has made a lot of money from the many expansion packs, and the board of directors has approved the sale. However, the regulatory authorities still have to give their approval.
