Makes resources more sparse than base game. You will need to use trains much earlier to get resources. Game will be more difficult especially with higher enemy settings.
Tweaks
Mod category: Tweaks
Small changes concerning balance, gameplay, or graphics.
Saltpeter-ore (Not sure which mod added this :( )
sea-oil (From Ocean Liners mod)
sulfur-ore (I think it came from a Nuclear mod, but I use a couple :X)
I would really need mod names to even try to add configs.
Nucular is supported - not sure what Nuclear mod you mean. No idea about Saltpeter ore.
Ocean Liners mod is not supported and it won't be - it's inherently not compatible with RSO. It changes game in a way that allows placement of ores and enemies on water so can't work properly with RSO.
