Let's re-rail this thread. We should discuss 'bout SVN rather than Chemistry here
I just had Kongo game.
It's practically
one of my favorite civilization now. It brings up exotic & fresh flavor to DoC that IMO, is pretty rare lately. Neither Moors, Poland or Tamil brings this flavor to me

-and their art is
awesome

I did not complete the game yet because of the WB Crash bug yet, but here's my thought so far :
1. I was about to point out that Mbuji-Mayi and Kindu is a different city
until I check the CNM and they are separated entry

.
In the game, the city name is
Mbuji-MayiKindu 
2. Perhaps the Impi attack should be reduced...?
3. 1 more Settler and 2 more Workers at start shouldn't really hurt the stability, IMO.
On the another half of the world :
1. What is the ratio AI Moors will declare war against AI Mali? They ended up friendly in my game because of Islam.
2. Islam in Mombasa & Quelimane.
3. Portugal should spawn with 1 less settler, since, iirc, the settler was given by Rhye so they settle the Casablanca/Morocco, that they always settle Ponta Delgada?
4. Arguim should not be settle-able IMO
