I realized eventually, that a randomization of the basic recipes of the game could add real flavor to each new game.
There could be an option to randomize recipes under the custom options at the start of each game.
This could include ALL ores and products, or be broken down into simpler terms for mainly vanilla game with subtle changes in mid-late game.
There would be no limit to what recipe changes could be made under "totally randomized" settings. Thus boilers and steam engines, may require copper; Copper wires could be made of wood...ect.
Obviously, you wouldn't have to play with total randomization settings, but it would add a challenge, and give your factories a whole new look.
I think this would allow for players to change the way they build their factory layout, each and every game. Reducing redundant "Cut & Paste" factories and, further reducing boredom, and limiting game burnout. *Something I'm very close to, and the game isn't even finished yet.
