The Sims 4 Growing Together: Personality Changes

TS4 personality traits growing

Sims can now discover new traits or swap traits through gameplay!

For the longest time, our Sims were stuck with the same 3 traits we picked out for them in CAS for their entire lives. Regardless of the direction their life took afterwards, there was no personal growth to reflect those changes in habit. The Sims 4 Growing Together changes that in a big way. Sims can gain an entirely new personality based on the way they live their lives. Their personalities grow and change alongside these new life experiences. See how trait changes work in The Sims 4 Growing Together!

Sims 4 Growing Together Trait Changes

As your Sims go through life, you may receive popups that give you the opportunity to add a new trait to your Sim’s existing set of traits. You might also get the opportunity to swap one of your Sim’s traits for its opposite! These Sims 4 Growing Together trait change popups are not entirely random; they trigger based on what your Sim is doing at the time. However, it can be tricky to deliberately trigger them. You’re not guaranteed to receive one of these popups every single time your Sim does a specific action. This creates a lot of variety in storytelling. No two Sims will have the exact same trajectory of character growth even if they lead mostly similar lives.

You are not forced to accept these personality changes. You can decline the opportunity to change your Sim’s traits if you wish. So you don’t need to worry about the game forcing your Sim down a path you don’t want. However, accepting these trait changes in The Sims 4 Growing Together at least some of the time can lead to more exciting gameplay you didn’t expect.

Trait Additions

You will periodically get the opportunity to add a new trait to your Sim’s existing traits. These are not reward traits; they are core CAS traits. This is exciting because additional CAS traits are normally not available to change or add to after you initially select them.

Each Sim can gain up to three additional CAS traits through gameplay. So in total, our Sims can actually have up to 6 CAS traits; 3 that you selected, and 3 gained throughout their life. You can really expand your Sims’ personalities in Live Mode using The Sims 4 Growing Together’s trait change feature.

Sims 4 Growing Together Trait Changes

For example, our Sim started out with the Loves Outdoors, Dog Lover, and Active traits. As she started learning new skills, she was quite clumsy at them. She would accidentally slice her finger while cooking and stumble while running on a treadmill. After a few of these incidents, we were asked if we wanted to give her the Clumsy trait. We said yes, giving her a fourth CAS trait. Later on, we had the opportunity to give her the Cheerful trait as well since she was frequently Very Happy.

New Personality: Family-Oriented

One of our other Sims had the opportunity to add the Family-Oriented trait to their existing CAS traits because he was spending a lot of time caring for his children. Another cool Growing Together trait change!

Trait Swaps

Additionally, Sims can have their traits swapped out for its opposite if their life is going in a direction that conflicts with one of their existing CAS traits. Our Sim met and fell in love with Marcus Flex, a premade Sim from the Get Together expansion pack. Marcus has the Noncommittal trait, so he is unlikely to want to settle down in a marriage. However, he and our Sim were extremely compatible and we thought she could be the one for Marcus. So we had him propose to her.

When he proposed, we received a popup asking us if Marcus should lose his Noncommittal trait and gain the Loyal trait, instead. We said yes and Marcus was a changed man thanks to the power of love!

This powerful feature allows for so many different types of storytelling and personal development in Sims.
