I checked the Nation ID Tag Thread, and there are only like 5 African Nations. Now, unless you just want the entire continant to be one country, you have to add more.
I'm thinking:
Egypt, Libya, Algeria, Morocco, The Congo, Mali, Liberia, Sudan, Ethiopia, Somalia, Angola, South Africa, Madagascar, Kenya, and Mozambique, at least.
Those are just the largest nations in Africa, and the ones that make up Africa's Political Landscape.
Somalia, Libya, Egypt, the Congo, South Africa, and Liberia all have very important Resources, or are very outstanding on the international stage. Also, many African Nations are a constant problem for the US, the US continiously having to step in to restore order to African Nations. And Liberia supplies the US' Rubber... So the continant has some importance... You can't just leave it blank!
