On a macro scale, most tribes or clans that we know of, and I mean tens of thousands of them, were practically the same, especially when taking into account their biomes. Obviously the Eskimo, Akkadians or Vistulans were different, but the differences between Vistulans, Polans, Mazovians, Goplans, Lendians and other west Slavic tribes…? Practically nothing. They lived in practically the same environment, dealt with the same resources, made the same things, talked the same language and so forth. Look upon the Grecians of old, the Boeotians, Minyans, Argives, Arcadians, Phocēans, Locrians and others… the fact that they went out together to burn Troy does suggest great similarities between them. Especially since Troy was similarly Grecian… The Iliad struggles to establish any actual difference between them other than just… happing to be living in different places. I feel therefore, that there should, most often, be very little difference between “our” tribe, and the ones close to us, or different clans or so.
Of course, @demon might be thinking more of the differences between groups of tribes or clans, “peoples” or something like that. After all, the differences between the West Slavs and the Germanic tribes next to them were such that the former called the latter something in the lines of “People who can’t speak properly”. They still do God knows they fought endlessly for the first one and a half millennia of their being neighbours, till 1945 AD… And just at the Slavs when they came to Europe, or when the Indo-Europeans came to Europe and the Middle-East, look at the Hittites, or even the Akkadian invasion of Sumer. In those cases, I would agree that there would be differences in culture, language, religion and other matters. Not very much so in technology, even though the Indo-Europeans are said to have come mounted on horses, and excelling in the use of Iron… but I’m sceptical towards two different clans in the same tribe being different from each other in abilities, unless it is more like the castes of India, with practically bred “merchants” or “craftsmen”. Especially so early as the neo-lithicum and chalcolithicum
@sakelariosak, I think the developers answered this in their interview ( http://www.histogames.com/HTML/news/2017/septembre/008-interview-avec-les-developpeurs-d-ancient-cities.php ), in which they stated both that:
“There will other tribes living around in the world, but not in the city map. You will interact with them, and them will interact with you giving a nice context for the city. What happens in the surrounding world will have an impact in the city.”
And that the game map, or well, the city map, will:
"… range from 1 to several Km² but we still don’t know how big they will be in the final game because we still need to implement lots of optimizations.
It will be enough to hold a medium city with surrounding farming areas though."
It seems then that it will be like Caesar III, Pharaoh, Zeus: Master of Olympus, Emperor: Rise of the Middle Kingdom, Children of the Nile or Tropico II: our tribe will live in our city, or village, on our map, and every other tribe (or other clans of our tribe? Other tribes of our people) will be accessible though some regional or world map, which will probably grow as we discover more of the world. On that regional or world map, we can do everything from found colonies, trade with other cities, invade them, create alliances with them… maybe they will affect each other, migration and spreading of ideas, languages, religions…?
