The highschool survey suggestions sound amazing to me as much as I want my Sims to go to class and I really do I need highschool game play and surely not playing as a teacher yawn, adults have more than enough careers and game play this pack needs to be all about the teens. Drama cliques would be great I dont need all my students walking around with a smile and sitting in a classroom only doing assignments would get boring fast without outside of the class story telling possibilites you dont seem to want.
Also I'm all for the things you mentioned like traits and different types of class rooms pe math and science but just because we get some drama game play tossed in does not mean we would not some of the things you mentioned. How I miss drama in the Sims I'm over always happy and I'm sure I'm not the only one.
