Also, if you did do another version, rather than Cabinda, I would use FNLA. Just a thought. Maybe a cool idea would be "The Border War" of Southern Africa from 1975-1989, involving Angola under MPLA control, South Africa, South West Africa (modern Namibia and SWAPO there), and then other period activities, such as ZANU-PF in Rhodesia and ANC activity in SA. I'd be willing to help in some capacity. Good luck, and thanks in advance for figuring out what that problem is that I have been having regarding this scenario.
