How about a school where every student is locked in the facilities for the education period and every class depends on each other. Each class is given a bit of resources
A farming class, a processing class, a cooking class, creative arts class, construction, wild life, etc.
The farming class has to farm for trees and raw foods and stuff for the processing class to work through (along with other materials for the creative arts and construction or whatever) for the cooking class when they're are no fish or animals raised enough to turn into food because stock.
If a class overuses it's resources without the ability to restock for the next week or if they do not reach quota due to failures or laziness then the class fails for the week.
Survival games are fun. Too bad something like this would be too hard to represent here without killing everyone.
