In his book The Goal, Eliyahu Goldratt explores the Theory of Constraints (TOC).
TOC posits: in any system, there is at least one constraint holding back throughput. Attempting to improve throughput anywhere besides the constraint makes the problem worse.
What does this have to do with a video game about trains?
While on the surface it’s just a game, Mini Metro is actually a great sandbox for practicing Goldratt’s ideas.
