Having recently read about Charles R. Saunders passing I read and greatly enjoyed Imaro: splendid prose, great world-building and pulp vibe. I look forward to reading the others in the series, and highly recommend them for a pulp-Africa setting. I'll probably take a look at the old d20/3e era Nyambe products by Atlas Games. I'm assuming, based on it's RPGGeek ratings, that it's got good inspirational material for AS&SH.
