A funky idea I just made up out of nowhere is to be able to make your own fraternity, as someone who's past their second year you can do something like pay a fraternity leader a huge amount to be able to own the whole building to do what you want with it to replace their fraternity, overthrow the leader and occupy their position by getting a good relationship with the other major members, or convince the leader that you actually deserve to be the leader by doing things to prove it (or you just build a new building with the approval of the principal/dean and whatnot with the help of the construction workers in town). And you can apply rules in your fraternity (like no shirts allowed or somth), pledge tasks for those who wants to join (and you can get events where you see people streaking a football field if you gave it as a task), initiation rituals, fraternity symbols, representing the fraternity, throw parties, claim due rent money, daily expenses/bills and whatnot.
