The teen life stage may serve as an important period in a Sim's development, as Sims can begin to build their first romantic relationships from this point onwards.
Most teen Sims will have a recurring want for their first kiss and to go steady with another Sim.
Teenage Sims have a later curfew of pm, which is an hour later than the curfew for child Sims.
Teens who violate the curfew will also get the positive "Out after Curfew" moodlet while doing so, whereas children do not.
Teens can also use gym equipment, and it becomes necessary in order to stay fit.
Teens in The Sims 2 are unique in that they can age up into one of two separate life stages: Young Adult or Adult.
Players can download custom head and body skins which can give a Sim the appearance of being a teen.
It is even possible for teens to run away if their relationship with their family is too low.
Prior to the update, Sims can only grow as far as the pre-teen life stage.
Sims in this life stage can be enrolled in high school.
If University is installed, the player has the option to send a teen to college, where they will first live as a young adult; otherwise they will skip ahead to the adult stage.
In The Sims 2 and The Sims Stories, when a child becomes a teenager, their aspiration can be chosen by the player.
If Nightlife or later is installed, turn-ons and turn-offs are also assigned at this point.
