Nyambe looks pretty interesting, though hard to get here in the UK (60 quid on Amazon, or ship it from America on Ebay for 3 quid and 25 quid shipping). Can anyone offer opinions of how it stacks up against Southlands by Kobold Press? It occurs to me that adding a well-researched Africa analogue to my homebrew setting might be a good idea, and that I'm very unlikely to ever develop the knowledge of Africa myself to do such a thing justice, so I'm tempted to pick one of these two up and slot it in.
