I see that the Scenario setup .xls 3rd sheet (cities) share most of the fields as the regions .xls, so I wonder
1) Do I have to modify the sce .xls and then copy and paste the data to the setup .xls?
2) What are the files I would create after exporting the file to csv? (I mean, I have already created new .rgn with modified names displayed in the map and then I have manually modified the terrain type in some of them, would I have to change then again, or would be other type of files the ones recreated?)
As you see, I still have to figure out how the mod process is. I would apreciate a kind of short guide, not a detailed one but a simple one in which the steps are summarized, like for example the first step I did
1. Modify geographic conditions in the .rgn files through the regions.xls file
