Glad to have you on the team Genghis_Kai! Obviously your work creating the GEM had already been a huge part of this mod, before you even found us.
The most up to date civilization/leader list is
here. I'm pretty sure the first post here is accurate too, I'll go over it.
All of those civs are in our CIV4CivilizationInfos file, and will be in the map I'll be uploading tomorrow morning.
1) Western Europe- exactly right.
2) Independent African states will be Morocco (capital), Libya, Zimbabwe, Kenya, and possibly others including one or more on the ivory coast.
Some countries in Africa will be failed states; (Somalia, Equatorial Guinea, Chad.). We can change these as governments fall or become unstable, war breaks out, etc. Perhaps someone can find a better list.
Others have their own civs (Nigeria, Sudan, etc), for some we can also use the minor nations civ; and then the rest will be African Union. The AU ones should be countries that are more closely aligned with the USA/west.
Africa is going to take some playing around with to get perfect. Basically it should be splintered as much as possible with the civs we have available to us. I think the idea is to have every African country represented by at least one city.
If you'd like me to start by taking a crack at they way I see us doing Africa and possibly the middle east, I could do that, you could improve on it and then do the rest. Or if you want to do it all, by all means please go for it.
