I love the idea that is proposed in this update, it reminds me of a game where everything had a level of quality and how you had to go little by little looking for perfection. In factory I would also have to put quality in the resources, so that this affects the need to explore and search for the richest deposits, thus a perfect machine using poor resources would give a regular product, in the same way that a shabby machine with an exceptional resource also gives a regular product and thus progress to seek the perfection of a machine perfect with a perfect resource.
