Firstly Phalanxia, I must say that I very much agree with your points and have been arguing them myself for some time. Africa in VIC2 is extremely poorly represented, it's like the Devs were going to make more countries but just made Sokoto and gave up (resulting in it literally just sitting there on it's own for the entire game, until getting conquered). I've pointed out the problems to the Devs several times, but they seem to be uninterested in doing anything (i.e. like when I pointed out that
Africa doesn't have enough Population, though I just fixed that one myself).
I, along with several other people, have just decided to mod Africa into a historical state and made many African kingdoms for
New Nations Mod and
POP Demand Mod, and we've tried to come up with game mechanics which allow them to be represented in a historically plausible way (which is often not easy within the game's constraints). We took a somewhat different approach to
Mod Tribal Afrique, in that we started from the position that only African kingdoms which practiced Agriculture and had an organised state structure (usually a Feudal structure with a King and Aristocracy, etc) would be represented as countries (so no disunited tribes like the Maasai, or hunter-gathers, etc).
The current version of NNM has 36 new African countries existing at the start and several more existing as cores. I recently created 9 new countries for NNM/PDM (mostly from breaking Ethiopia up into its constituent minor kingdoms), though they haven't been integrated yet you can download them yourselves (the posts about them start
here). The current version of PDM has (I think) 21 new African countries at the start, but the next version will add 3 more and I think Rylock intends to gradually add all the NNM ones before AHD is released. So in the end PDM will have a very good representation of Africa.
Here's what Africa will hopefully look like with all the new starting countries added: (link to

There're 45 new kingdoms existing at the start in that picture and maybe another 5 or so, existing as cores, though I do have long-term plans to create at least one core for every province on the continent, to represent all the smaller cultures who exist as POPs but never had states. This setup still has about half of Africa as still "blank" and the normal colonisation mechanics are still used there, which I think is appropriated since there were no organised states in those areas (that I know of). I've also recently started doing little write ups about each of the new African countries on the
PDM Wiki, so players can get familiarised with these, totally historical, but obscure kingdoms (for example
Ashanti,
Dahomey,
Kongo).
I'm glad that people are talking about this issue as I think the Devs think that no one cares, so if people continue to raise it they might eventually listen, but for the moment Modding is the way to go if you want to experience 19th century Africa.
