If the University expansion pack is installed, teens have the option to go to college, where they will be young adults for approximately 24 days. Players will need to build up talent badges, skills and relationships with other people, so that they can be successful in their career.
A player will also need to make sure a Sim is happy and well by fulfilling wants (including lifetime wants, avoiding fears, and fulfilling motives).
The game contains some time-bound social challenges that provide a reward if successful.
Sims can throw parties to gain aspiration points or invite the headmaster over for dinner in order to enroll their children in private school.
A Sim will be born when a female Sim and a male Sim try for a baby.
The mother will spend 3 Sim days (each day lasts 24 minutes though time can be sped-up) pregnant before giving birth to a baby. The baby's appearance and personality will be based on the genetics of its parents (though the baby's appearance is hidden until it becomes a toddler).
Sims can travel to Community lots in order to purchase things like clothing and magazines, and to interact with NPCs and townies.
The player can choose between playing a pre-made inhabited lot, moving a household into an unoccupied pre-built lot, or constructing a building on an empty lot. The player switches among the "live" mode (default) to control Sims, the "buy" mode to add, move or delete furniture, or the "build" mode to rebuild the house.
Instead of having to choose from already finished faces which include hair, it is now possible to alter the facial structure (e.g.
widening the nose, thinning the lips, elongating the chin, etc.) and choose any hairstyle to go with it.
Buy and build mode cannot be accessed when on a community lot, but can be opened by using the neighborhood view.
