Basically, Production Line is Henry Ford Simulator and that’s Brilliant

You can play any video game as long as it's this. Every second in Production Line counts. Lost seconds mean queues, which mean lost profits and, sooner than you think, bankruptcy. This is a game about assembling a car factory like the innards of a clock, where each machine does its job perfectly in-sync with countless others: finishing up its product just as the machinery next in line is freed up. All along the chain every machine must be always working, never waiting.
