So that's how it worky..... nice I know you didn't intend but now I figured how to do the LimitedNationsList....
Malibu43, it takes a little bit to understand, but now that I'm working with the folders more and more... the User\Saved Games\Thirdwire\SF2 Game is for modding only. In KB's example, that CAMPAIGN folder is in the User\Saved Games\Thirdwire\SF2 Game. So when you place it in that folder, the game will read it, and therefore you can mod to your content and whim, but the main install, like "C:\Program Files\Strike Fighters 2\etc. etc. is that, the base game files. So you can mod all you want in the "User..." folders and files, by placing them there, without messing up the core game files, which is of course something we all do sometimes. When updating it with a new patch... probably solves the "clean install" (not sure on that) by just updating the files without having to restart everything.
