Kongo is quite weak due to low/unreliable faith generation. I suggest giving Kongo the following:
Allow building of Holy Sites and their respective buildings.
Nkisi to give faith for artifacts, sculptures if city has a holy site.
Mbanza to give 1 faith per 2 population point.
Buff religious world wonders, some are laughably bad:
What counts as a religious wonder:
StoneHenge, Kotoku-In
Allow purchase of missionaries for cities that has a religious world wonders.
Additional religious pressure for cities that has religious world wonder. Religious tourism from cities following your religion that has religious world wonder.
Religious spread after completion of religious wonder.
Stonehenge: Unlock Pantheon and Great Prophet after building (weird to grant GP while blocked from founding a religion due to absent pantheon)
Kotoku - In: Keep + 20% faith, remove warrior monks.
Change religious victory:
Player wins a RV if all religious wonders are built and the cities that possess these religious world wonders follow player's religion. (We should also prevent razing cities that has a religious world wonder).
The RV idea unfortunately wouldn't work bc if someone razed a city, you are screwed. Example:
Norway: razes a city with Stonehenge.
Player: Oh crap guess I gotta go domination or culture now.
You get the point. However, If cities with wonders could be razed but the wonders stayed (so other cities could get them) that would allow for your idea along with fixing my annoying wonder problems.
