Introduced in The Sims 2: University, a Sim's Lifetime Want (or LTW) is a special want that represents the Sim's ultimate goal or something that would make his or her life "complete". Children and toddlers do not have Lifetime Wants. After a child (or a PlantSim toddler) grows up, and his or her aspiration is chosen, he or she will receive a randomly selected Lifetime Want. As a rule, the Lifetime Want will not be selected until: 1. * One of the Sim's wants is fulfilled 2. * The player saves, exits to the neighborhood screen, and returns to that household.
