First thing that comes to mind is an overhaul mod for OpenTTD which has a "Steeltown" economy that resembles the AIST Steel Wheel.

Neat, thanks for sharing!

You don't even necessarily have to leave Factorio to get that. The "Angel's Smelting" [1] mod, among others, adds a substantial amount of realism to the process of creating metal products from ores.

Cool! Of course there's a mod like that; what I was expecting? Thanks for the link :)
