If you ever give it another shot, I’d highly recommend going vertical with your factories. You can do each step of a production chain in a different floor to keep your factories smaller. As the machines in the game are very large, verticality helps a lot with the space management. Another tip to make it less complicated would be to use the satisfactory tools website. There you can specify production per minute for an item and it lists you the whole production chain.
Not gonna lie I was very biased against this game due to its track record with epic exclusivity, but I’ve heard great stufd about it and been having lots of fun so far
