An extensive overhaul, emphasizing detailed and realistic chemistry, materials, and production. Extends the base game to marathon-style scope and difficulty.
Basic first aid requires phenol to make. However, it can be researched before any phenol crafting is available, making the player unable to craft it. Ideally, this should be avoided.
However, I’m not quite sure how to do this best. There are two ways to make phenol:
“Crude Phenol Washing”, unlocked by the tech with the same name;
“Phenol from Cholorobenzene”, unlocked by “Hydrocarbon Chlorination”.
It seems that either of these technologies can be researched before the other. Ideally, basic first aid should be researchable after either of them has been researched, but it’s probably impossible to do that in Factorio.
One possible solution that I can see is to make “Hydrocarbon Chlorination” depend on “Crude Phenol Washing”, because it seems to be a more advanced version of producing phenol, and then make “First Aid I” depend on “Crude Phenol Washing” as well, because then it’s guaranteed to be the first available method of producing phenol.
