Which expansion pack should I get next?

I like Discover University for the most part but, I was very disappointed that you can't place a household in the dorm and play with them as a household. You can only play one sim at a time. If rotate, the grades of the one you aren't playing are affected as well as ability to enroll for next term, which is frustrating for me. Videos by game changers are easier to look up and they covered most of the packs. If you search ea game changers gameplay videos with specific game pack name you should be able to find them. And I find Carl's Guide gameplay videos informative as he seems to be very honest about his opinions on the gameplay/packs. He also has guides online you can read through that are very informative about gameplay.
