In a lot of forum threads when the best or top-tier civs are discussed or ranked, Kongo never seems to be mentioned much, or reach the top tiers. This really confuses me, because to me at least Kongo has a set of extremely powerful bonuses and is capable of having the best economy of any civ, and in my opinion the best civ for cultural and science victories. I'll explain why below. Before going further, I just want say that I'm only considering single player. I understand that a powerful mid-game economy won't do too well in multiplayer if theres a Sumeria or Scythia nearby ready to trample on you in the classical era. So, Kongo is famous for not being able to build Holy Sites or found a religion. Its the only civ completely locked out of a victory condition. However, I think its bonuses way more than compensate for it. So, in no particular order: Bonus 1: Relic, Sculpture and Artifact Bonuses - Each GW of these types produce +2 Food, + 2 Production, and + 4 Gold. This is fantastic because it means you get these extra yields without having to work tiles. A lucky start will give you a relic hut, and an invaluable + 2 Production in the first few turns. The Food and Gold are always useful at any time. Kongo is much more likely than anyone else to get the Sculptures due to its double Great Artist points bonus, so there is natural synergy there. The best part about this bonus is that themed Sculpture Art Museums and themed Artifact Museums give double the bonus yields: Meaning you get +12 Food, + 12 Production, and + 24 Gold without even working a damn tile! That's a truly amazing bonus that require only a small amount of effort to set up. Bonus 2: Double Great Merchants and Great Artists (all three types) - Commercial District is already the best district in the game so you'll want to build lots of them any. With Kongo you get twice the Great Merchant points, and Great Merchants are one of the best Great Person types in the game and are always useful, and some of them synergise really well with cultural victory which you're likely going for anyway. Double GWAM points means you will soar above most other cultural civs. The only hard part is having enough slots... Even if you don't want to go for cultural, and fancy say science, you can sell the excess GW for lots of GPT or other goodies. This bonus over all is so powerful it makes Brazil look like a joke in comparison. Bonus 3: Mbanza - A medieval era +5 Neighbourhood, still easy to place despite its supposed restrictions, and also gives + 2 Food and + 4 Gold without working the tile. Makes Kongo indisputably the best civ for going tall. Bonus 4: Starting Bias: Rainforest is really good in Civ VI. It offers a balance of yields, defensive tiles, and seems to give more than average number of amenities. Yet despite all these bonuses, Kongo is rarely mentioned as being top tier... Why?
