Africa's climates are quite varied as well. My parents just got back from a well digging project in rural Ghana, which is tropical, while the north is Mediterranean and desert, while the far south is temperate, quite similar to Europe. Not to mention the Savanna grasslands. I've seen most of those climates in the FF series.

What is less visible in these games is traditional African achitecture. The heaviest influence there seems to be European, with a lot of traditional Japanese thrown in (Wutai in FFVII for example).
