It's called Cracktorio amongst those who play the game regularly for a reason. Factorio is the very definition of the "just one more thing" game. I've seen the sun come up too many times after long sessions, not realizing how late (or early) it was. An endless way to reorganize and optimize, you can spend hours building the perfect factory. You get another item on the tech tree, realize you get to change up and add more to the factory, and the loop keeps going. It's THE automation game, and one of my favorite games of all time.
