Hi, I like your game. But I have some suggestions.
1: the language of the Iberians is incorrect. The Basque language is not an Iberian language (in the sense of a language of the Iberian peoples). I understand that you have put it because the Iberian language does not know how to translate, but it would be better not to put any Spanish language to the Iberians so as not to make historical mistakes like this one.
2: The melee units when attacking the buildings could be do as if they were throwing torches to make it more realistic.
3: I guess you already know this, but a military tutorial to explain the things that are missing in the economic tutorial, such as borders, etc ...
4: Going back to the Iberians, I would change the design of the ibera priestess to a more historical design. We do not know anything about this, it's true, but you could approach a more realistic design by simply taking Iberian elements. You can look the Lady of Elche, it is true that we do not know exactly what it is. Most historians believe that attire corresponds to the clothes of an aristocratic woman by other excavations where that attire is documented. Others think that it is a kind of priestesses. And the least defended hypothesis is that of divinity. But you can put it as a priestess or draw on it to create a new design more realistic than the current one.
5: The texts some have historical errors or exaggerations, very understandable thing (you are not historian). What I would like there to be information on each unit later, at least to know its functions better.
6: A clearer panel of the characteristics of the military units, that is to say, that you do not have to put the course of the mouse on the shield with the sword to see it. But the latter does not matter.
7:Pericles was an Athenian politician, but he was not a military man. So I would replace it by another Greek that were military.
This is not important, since it is historically good. But I would have put Vercingetorix with a Celtic chain mail and a helmet( protec the head is very important). It is good that you have put on a Greek armor, since it could have been obtained by foreign merchants or by steal it from a Roman. It's a matter of taste.
I'm sorry for my English, I'm not very good with languages. I wrote one that is specializing in military issues and is in the last year of the History career. One thing seems to me one of the best documented games I've seen, my congratulations, although you have to polish it. If you need help, you can count on me.
Friendly greeting.
