The Sims 4’s Traits are the characteristics or qualities that belong to a Sim. Some of them were released with the Base Game, while others were added with the release of The Sims 4’s Expansion Packs. Usually, every new Trait will be related to the new Pack one way or another, like the Maker Trait from Eco Lifestyle.
