Factorio!

I was playing my "spaghetti and make everything a mess" save (that has 'fun' mods like Scrappy Industry (where almost every recipe has a low chance to produce different types of scrap instead of the intended product) and Renai's Transportation (why build a belt around your factory when you can throw the iron plates halfway across it?)). I'm planning on updating the base to use "dropoff" trains, where the locomotives literally decouple cargo wagons to let them load/unload while moving around to deliver other wagon sets, at the cost of complexity in knowing when a set of cargo wagons is ready to be moved to the next stop. But hey, isn't that the fun of playing an engineering game?
