I feel like they should come out with an expansion pack focused on the teens and their gameplay. Some features could be...
-They could bring back the teen party from Sims 3 where the parents would go away and the teens had a party.
-They could bring back the sneak out after curfew interaction from the Sims 2 where the teen would call their friend in the night to pick them up.
-From the Sims 3 when parents teach their teens to drive.
-More school activities as in prom, graduation, after school clubs, and school trips.
I really think they need a separate expansion just for teens to make the teens actually feel like teens.
