Yeah, see, but you're forgetting lovely things like high background counts over god knows how much of the continent from centuries of grief and suffering, chaotic tribal lands that make Africa today look positively stable, a nation full of people who eat people, angry spirits looking to wipe the Kilimanjaro mass driver off the map, MASSIVE shedim infestations, and the fact that most of those mineral rich areas are under the thumb of a single corp that runs the area. Oh, and there's the fact that large parts of Africa make Humanis look positively tolerant. And the lack of any real matrix coverage over most of the continent.
As I said, there are a couple places worth talking about, namely Azania and Egypt, but other than that, there's only a couple sprawls in the continent worth mentioning, and all of them are best left to local players, since out of towners stick out worse than a troll at a dwarf family reunion.
Sure, there are things happening there. But there's many, many, many more things happening in Seattle, Neo-Tokyo, Hong Kong, London, DeeCee, Denver, and so on.
