So I've been working on this and I've gotten to a point of testing it, however, I can't seem to get the directories laid out correctly as nothing is changing either yes it worked or ending in horrible results, it's just doing nothing.
From what I understand the directory needs to match the game directory So one creates ModFolder(with xml's in there). That mod folder then needs to be laid out as the game folder. So based on the game folder, I start creating sub folders in the (ModName) mod folder.
DLC ->EXP4_Retribution -> Game -> ArtifactImprovementsDefs.xml
The one thing I don't understand is the ModdingReadme file says all mods must include ParticleScripDefs, Text, Core, Game. I just copied the example Mod folder, which had those folders all in there. There is nothing in those folders but they are there. Am I missing something?
