In this DLC, it's all about college-level education. You get three types of campus areas, along with a handful of new policies related to the educational system in your city. Building a campus requires a lot of space, similar to the previous industries DLC, for some buildings. At release, things were a bit shaky with citizens not going to specific colleges and so on, but that was fixed with a few updates afterwards. You still might need a few hours of gameplay to really get the hang of how citizens distribute, how campuses level up, and so on. I had a lot of fun fiddling with free education policies and ramping up tuition to max all of a sudden.
