How about the ability to make your own schools and setting what's taught there. That way you could have any type of school or university you want in your game instead of only one or a few to choose from.
Maybe options to set school uniforms for child-teens and set school hours. New activities and events like field trips, school dances, student elections, project fairs, and graduation. The ability to create school dormitories, set who's attends like vampires or other occults, all girls or all boys school... Make private or public schools. Gain school ratings and credibility...
Basically a schooling/education system that could be built upon with content released in past and future packs. Make an all vampire school that's open only at night, or a culinary school for aspiring sim chefs! Private school, military school, school of the arts, Hogwarts
