Show numbers and create a story,
It is so easy for people to overlook the importance of a story or narrative when designing a civilization. Sure, the civilized is can educate people a little, but whatever the design package is, it needs to quickly and easily communicate what playing that Civ is about. It’s literally like a meme. If you don’t have
something to work with the civilization design probably won’t be that popular. I would suspect that the Mapuche are near the bottom of Civ popularity, and a lot of that rides on their obscurity leading to a lack of memetic narrative. If I give you the Mongols, you instantly grasp mounted warmongers, for example. Our current iteration of Russia- the expansive tundra empire- is instantly digested as a player narrative.
Even the Zulu are built around a story, namely isandlwana / related battles, and that is enough memetic fuel to have gotten them into every Civ game. Literally go look at 20 years of firaxian zulus- Shaka + Impi + warmonger.
If a culture lacks writing and written records, as a
huge number of choices in Africa and the Americas do, our only recorded knowledge of them will come from people who do have that ability: either contemporaries, or archaeologists. This can make it almost impossible to build a good Civ design out of such a limited perspective. It may not be fair in some sense, but think of all the prehistoric tribes and cultures - other than separation in time, I’m sure many of them would be just as compelling as some of the groups tossed around in these threads.
I think it would be interesting to see if there were any very populous regions that are not getting represented, and to understand why exactly that was happening.
I think post colonial nations have mixed reception (although they can be well designed and fun!) and if you set those aside, huge swaths of the planet are literally European controlled territories going back centuries.
But the world population distribution used to be extremely lopsided in favor of Europe/Mediterranean, China, and India. Which makes some sense as to why so many Civ’s come from these places. The populous American cultures- namely Aztec, maya, and Inca, are all in the game routinely. Cultures that don’t build permanent cities, like many North American groups, are just hard to study. No one’s fault.
Look at Kongo- certainly qualifies as a “diversity” pick- their population is estimated as a fraction of a million during the time of Mvemba. And this is the populated part of Africa! So I think historically Civ has done a pretty good job at including
population with its Civ choices- without the people you can’t have any narrative.
It’s not just about including civs that have never been included, you need to be able to sell a story (which may be a stereotype) in a few seconds of browsing the selection menu. Civilization Uniques are literally core to this entire strategy. This is also why the generalist civs are also the most well known- the name by itself gives enough background for most people. A lot of the more obscure ideas in this thread are just hard to design around. Especially if they did not write things down so we have very little idea of who the leaders were, key historical events, etc.
