All the worlds in Sims 2, 3, and 4

How about sub-saharan africa? Kenya in East Africa has the major city of Nairobi, plus the geography of savannahs and forests, a major river, etc etc. And we already have rainforest/jungles, and deserts, but no savannahs. The entire African sub continent except Egypt, is conspicuously absent from the games to date, and Egypt doesn't well represent most of the rest of the continent.
