You still need to work on this mod. You didn't put the files in the right folders, which makes me wonder if you have actually tested it. I'm not completely sure as to when and how, but right after I researched the Industrial Age, I got an error and the program exited. I think it may have been after I clicked on the barracks after researching that age or just right after it. Either way, it would seem you have an error in your mod. The error said something like "very bad unit gpiece"
As far as I got, which wasn't too far, your mod isn't that bad. I liked the idea of cloaked ranged heavy infantry for the gunpowder ane enlightenment age. Unfortunately I could not take a look at the stuff beyond the englightenment age as the game crashed. You know what you are doing, atleast partially, but you still needed to go over your mod and revise it, it has some errors.
