by

Okay, fellow Sims players, get ready! Things are about to get awesome in The Sims 4. The Adventure Awaits pack drops on October 2nd, and next week we’re getting a new event called Forever Friends. Both are all about childhood – think imaginary friends, hanging out at the playground, and even summer camp! I’m super excited to create some new memories for my Sims.

The developers of The Sims 4 have released a free update to get players ready for future content. This guide explains the new features included in the September 2025 update.

Everything New in The Sims 4 Update (09/18/2025)

Here’s what players can expect to be different in *The Sims 4* after the September 18, 2025 patch: new features and improvements.

Base Game

  • Playground Venue

The Sims 4 has added a new type of location called a playground. If you designate a lot as a playground, you’ll find it’s mainly visited by kids and the adults who supervise them after school.

  • Venue Type Filter

The upcoming Adventure Awaits expansion for The Sims 4 will introduce custom venues, giving players more options for where events take place. To help navigate the variety of lot types, the developers have added a filter to the event planning menu, making it simpler to find the perfect location.

  • Play Pretend Interaction

Okay, so the new Adventure Awaits pack is seriously boosting the imagination factor! My Sims kids can now just *pretend* play all by themselves, or with their siblings, which is awesome. There are a bunch of different themes they can choose from – they can build a fairy tale castle, play house, pretend they’re stranded on an island, go on a pirate adventure, or even become space explorers! It’s really cool seeing them get creative.

  • New color for the Slouch Beanie

The Slouch Beanie hat for teenage and adult Sims now comes in a new color! Players can choose a light, off-white shade called Ecru when creating their Sims.

  • Memory Boost feature (Early Access)

In The Sims 4, players will soon be able to use a feature called Memory Boost to help improve game performance. It will be available starting September 23rd as part of an early access release, and you can turn it on within the Game Options menu in the settings.

When you turn on Memory Boost, the game automatically saves your progress more often. This helps keep the game running smoothly, prevents unexpected crashes, and minimizes slowdown or choppy visuals.

Island Living Expansion Pack

  • Bassinets for Merfolk

In *The Sims 4*, many supernatural Sims are born with a unique bassinet. Mermaids were previously an exception, but now they also receive a special bassinet when they return home from the hospital.

Life and Death Expansion Pack

  • Soul’s Journey Balance Adjustments

We’ve updated the Soul’s Journey system! Now, your Sims will earn Satisfaction Points every time they reach a new milestone in life.
