Hello Dylanwtn Welcome to the site.
Surely an interesting idea you posted there.
It is indeed an ambitious idea.
I'd love to make a mod along those lines, but a few problems I think of right now, and which have somehow stopped me from continueing with modding CI aswell are these:
-For those new nations, one would need the AI source code badly otherwise it makes no sense to create all these new nations, unless the mod is intended for online play. At the moment I do not posess the source code to do this.
This is the main reason why i switched to modding CII at the moment, because the ai comes in open xml format which is a lot easier to modify and create new one's.
-Secondly, for all those nations, a lot of new models would be needed, not only are they a lot of work to make, we would need someone who can do this for us and is willing to do so on a free bases.
Surely the idea is good, though I strongly doubt that we will find enough people to get the job done and aswell the much needed source code for both the AI as the engine, as I have failed to obtain it untill now.
I could sent another mail to GSC requesting it, but I somehow doubt they will reply will a positive result.
Kind Regards
