a overhauled personality system where the main priority of sims decision autonoumusly are based first on the Traits rather than emotion, An Aspiration system where the goals are not specific, A proper memories system that affects a sims behavior, and an emotion system that dosen't overpower traits. I"ll also go to the fact that a sim has many interest in their life, such as skills, and while this might sound like sims 2, Wants and Fears. Its the deepest system they ever introduced in the franchise. It needs a big debut if they want depth for sims in The Sims 4
