The first step you will take in your journey while playing TS3 (The Sims 3) is by making a Sim. It is ideal to make just one Sim if you are a beginner so you can get used to a Sim first. Sims are like humans, they have moodlets, needs, traits and more! You can choose 2 traits for a baby Sim, 3 for a Pre-Teen, 4 for a Teen and 5 for a Young Adult and older... Then you need to sort out their fashion. What clothes they'll wear, how their hair looks and even the more detailed parts like the eye sockets, the shape of the face, etc.
