You can play all The Sims 4 expansion packs at the same time, as long as your computer can handle the additional content.
Expansion Packs are designed to work alongside the base game and with each other, so you don’t need to choose between them.
Content from different Expansion Packs can also be used throughout your game.
However, if you’re playing on a low-spec computer, having multiple packs enabled can affect performance.
You may experience more lag, longer loading times, or other performance issues, especially in larger households and busy lots.
The biggest downside of playing with lots of packs enabled isn’t necessarily performance, though. It’s the amount of extra activity and notifications that can appear during your gameplay.
One of the most annoying things about playing with multiple Sims 4 expansions is getting notifications about events, activities, and features that have nothing to do with what your Sim is currently doing.
With several packs enabled, the game has access to a huge number of gameplay systems.
As a result, your Sims may receive notifications about festivals, events, special activities, neighborhood happenings, and other pack-specific features.
If you’re trying to focus on a particular storyline, these notifications can quickly become distracting.
Instead of concentrating on your Sim’s family or current goal, you may find yourself constantly dismissing notifications about things happening elsewhere in the game.
