Someone then played around with the idea and prototyped a "efficient Yand Sim" where the student routing system used the built in Unity pathfinding tool to get rid of that headache of spaghetti code.  Another big problem was that a lot of the assets used in the game are just bought Unity assets that have unoptimized sizes for what they offer for scenery.
