I very much doubt that. I personally laid down rail in every province that produced iron, coal, timber and the like that I could. I had all of Africa that produced those and had maxed RGO output and rail techs. I was #1 in most raw materials and had an overwhelming lead on intermediary goods like steel, at times more than half of world production. The rest of the great powers had maximum rail save for Russia as well. Iron demand was double the production and canned food triple. Not like world was crippled in anyway.
I said this before, but RGO production is not the problem (as neither military consumption doubling is). Increasing the production of RGOs just means the bottleneck kicks in when you have a higher number of soldiers. This presumably would just give you a bigger army and make the game easier for the big powers.
Yes, you said that and I disagreed. Raw materials aren't enough to support great wars. It's as simple as that. I have 2.2% soldiers and I'm not using half of those. #2 Britain has 50% more brigades than me. Everyone mobilizes of course and that pushes the demand over the edge. What are you proposing, great wars without mobilization?
Do not fight against countries capable of fielding expensive brigades if you cannot afford them yourself. Or, save up money before the war, train the brigades, fight the war, disband the brigades and spend next 10 years recovering from that. Think twice before getting into war and give up land in crisis if you have to avoid a war.
Good luck playing Ottomans like that, game is trying to enforce Sevres treaty by 1850 if you just let them be. I wasn't bothered with the costs as Germany but I totally dominated world industry and most of the raw materials as well. War time was still making me lose double the rate what I was earning peace-time with 0 military slider. I can expect what smaller countries are going through.
Or you can pull back for a few months, set up a line, then turn down the military supply sliders, so your construction can start, cuz I mean, the GP's in WW1 totally went balls to the wall every day, never ever sat back and built up for an offensive.
Yeah, they pulled back, turned down the canned food they gave to soldiers on the front, then trained their tank brigades. That's what happened in WWI, right?
"General Allenby, you're required to pull back from Jerusalem to Sinai since we'll be training some tank brigades for the offensive on the western front."
