So, after seeing the achievement, I decided to do the challenge, even though I'm not a great player. The goal is to control all of Africa, as Kongo.
For this first try, I decided to start at 1444, even though it's maybe not the optimal nor interesting start date (1575 starts with a portuguese colony right next to it, allowing for westernization, and it's your first neighbour !).
So :
Kongo, 4 provinces, religion shamanist, culture konguolese (Anziku is Aka though).
Tech group sub-saharan (200% cost, -2 monthly power), tech lvl 1.
Tribal despotism, +1 revolt risk, -100% provincial trade power modifier, -10% core cost. Incapable ruler can apply if more than 10 cities are controlled.
No neighbour, one coastal province.
So, what the hell I am gonna do ? Tech up, even if it's really slow. Admin is obviously my focus, to unlock ideas.
First, I have to reach admin lvl 4, and here I think I'll take the exploration idea, to be able to expand a bit (even though natives are really strong, I will maybe use some military power to tone them down a bit). Then, I hope to go for tech lvl 7, where I'll take innovative ideas, for 2 reason : help me tech up, and allow me to reform my government (you need either administrative, economic or innovative idea completed to reform).
Expected cost :
Admin : 6 lvl + 7 ideas = 10,000 ! Nice, a round number. As I have base 1 admin point, I hope to maintain an average of 5 admin points per month (3 ruler average + I can afford one advisor, so should be possible). Even like that, it would take me ~166 years (1610 !). I can reduce the cost of each idea by 5% with the advisor -10% (it's 10 percent of the base 600, so -5% for me), which would reduce the cost by 360. Stability shouldn't be a problem, as I have a neat little trick, so only core could slow me down. On the other hand, if I meet westerners before completing, I might or might not westernize first.
I won't spend my points (on tech levels) unless it's for unlocking an idea, or I'm at max power (1998), or I have an advisor which reduce the cost.
Diplo : I don't really need diplo tech, but I'll still get them. In the exploration group, I want the 4 first ideas, so a cost of 1600. Should be easily reachable.
Military : It's not my main concern, but important if I want to wage war on future neighbours (if I manage to expand to meet someone).
I'm going to get the ball rolling, but it's really slow, and the first updates will be really boring I guess.
