Mod of historical accuracy overhaul?

[GrimPixel]

Playing this history-themed game, I was amazed at the first glance. When I look into the details, ah, it's first a game, then history-themed.

I see there are some people posting detailed introductions about a civilisation or two, like that Kush one. As for the other, I am not sure about them. What technologies does the civilisation employ? What kind of philosophy and policies does the civilisation adopt? What kind of unique weapons does the civilisation have? Such questions are unanswered or answered with flaw in this game.

I would like to know your opinion.

This game does better than most at historical accuracy, but it's not possible for any game to be totally accurate. Reality is too complex to simulate in a game, and gameplay quality is important too.
