I'll add to that Africa's geography is fucked... the coastline is old, smooth, and shallow which means you don't get many ports. On top of that, the African escarpment means that interior rivers tend to have huge rapids that are basically unnavigable. All of this greatly complicates logistics and hampers internal trade... for instance, getting minerals from the east Congo to the Atlantic requires ~9 different transports (e.g., switching back and forth between water and land vehicles). Europe and North America, by contrast, have an embarrassment of riches... loads of glacier-carved deep water ports, extensively navigable interior rivers, and (at least in the U.S.) lots of inter-coastal waterways.
Geography isn't the only thing that hindered Africa. Tropical diseases and the Tsetse fly also fucked things up pretty well by devastating livestock populations. Cattle means you can farm more land with fewer people (and fertilize it too), plus they're a food source. I'm sure there are other factors too, but these are big ones that would inhibit any would-be society.
