Also to consider is the fact that with oxygen being relatively scarce in the atmosphere of Mars, even should they exist, fossil fuels would be rather difficult to exploit and a counterproductive effort on top of that.
That was as far as I made it with the thought, but I am left wondering what would replace these cargoes and industries in a Mars setting, even if in nothing more than a custom LNG file.
Any colonization effort of Mars (or any extrasolar planet orbiting α Centauri, β Centauri, Proxima Centauri, etc - the list of which keeps growing) would need water. But replacing "Oil" with "Water" would still leave us with an Oil Refinery and "Diesel" to deal with, so the end product "Diesel" would be a better choice to relabel "Water". But what to do with the Oil refinery and Oil? Maybe "Water Purification Plant" could replace "Oil Refinery", but I'm left pondering the replacements for "Oil Well" and "Oil".
"Coal" is a bit easier. Replace "Coal" with "Minerals" and relabel the "Electric Plant" as "Atmospheric Plant" or "Terraforming Facility".
Also, in such a system, water would be too precious to use as the cooling agent in a thermonuclear power plant, so the current model for "Nuclear Power Plant" is a bit out of sorts. Assuming I went in the direction of a tokamak reactor, a new model would be simple enough to make. And a "Uranium Mine" could be relabeled "Centrifuge" (a nicely vague term) and its output relabeled as "Isotopes" (also a nicely vague term).
And very obviously, the house models would all need replaced. And the farms... which will be problematic. It would be easier with the animal farms since they don't have any trees associated with them.
And speaking of trees, what then to do with "Logs", "Pulpwood", "Lumber", "Furniture", "Logging Camp", "Lumber Mill". "Paper Mill" and "Furniture factory"? It's not even out of the oven yet and this layer cake already has too many layers...
