Hey there
So I tried your mod today, easy to install you place it in your mod folder click that run button and that's it. I had no issues there.
Going to give you feedback of how I played the game.
So I started an advance start in the modern era ( I know easy, but I rather see biological terrorism than gunpowder terrorism). Small tectonics earth map. I started in Asia and took Australia, when I went to try and kill my neighbor the french I learned of a new option in this game,( alt click) black ops and the political thing. Overall I loved the whole thing.
Anyhow I was the only terrorist state through out the game and I had a angry native score of 5000 which I felt proud of. Really American of me.... I kid. The barbarians(natives or whatnot) where easy to kill however became VERY annoying, even at a angry score of 100.
I had enough of them, so I put a unit on every empty tile in my empire, naturally I was #1 in power and #1 in soldering there after NIHAHAHABUAHAHAH. Anyhow this solved the problem of barbarians popping up. I had conquered the French north of me and next where the persians who lacked ability to make a navy.
It was a full out nuclear war and once my units where off the tiles in the north barbarians arise after war calmed down. Not really a problem though I had two cities up there and they where a nuclear wasteland so the barbs did not bother me much. I had bigger worries.
Okay so I ended up razing 4 of the Persian cities and won the war....I stopped playing after I started looking like I was going to win (really don't feel like placing a unit on every tile again and cleaning fall out haha

)
*The game played well to me I had no problems but these.
I could not tell the difference between indigenous and terrorists... maybe they where one in the same? I... don't know. Not a big issue.
I wish I could have more control of terrorists, playing the game I expected to make terrorist units that could carry maybe nukes, anthrax, bombs, incite riots? Again not a big problem since terrorists would nuke stuff all the time anyway
Speaking of nukes, maybe I am a noob but I launched around.... 20 ICBM's against Cyrus(or more)
All of them where shot down...bad luck I guess. I launched around 70 tactical nukes throughout my game and 1 out of 10 times did it get shot down. SO usually when I do nuclear warfare atleast 1 ICBM goes through and tactical nukes got shot down fairly often at a better rate than here. Now maybe I got lucky or, something with nukes is messed? Suggest you check that bit out.
Other than that GREAT mod, I had fun.... but I did not like the fact that everyone hates the terrorist country with a passion and no one wants to join my empire of dooom

I wrote quite a bit, sorry heh. good mod.
