The Sims 3 features a brand new engine that allows you to immerse your unique Sims in an open living neighborhood where they can roam and explore all new surroundings including the beach, mountains and town center. The neighborhood is alive and constantly evolving so what happens to a Sim on one side of the neighborhood could impact your Sims on the other side of town! If your Sims are in the right place at the right time, who knows what might happen? And now for the first time, your Sims have distinctive personalities thanks to a range of all-new personality traits. You have the option to select from dozens of personality traits such as brave, artistic, kleptomaniac, clumsy, paranoid and romantic. Combine up to five traits to create an endless number of truly diverse individuals.
