Well, Persians did use Scythian battle axes, or sagaris, so they would look similar, just not like that AI image, but way more slender: Here some discussion about it (and more representations): https://www.oeaw.ac.at/ifi/blog/detail/the-scythian-sagaris-single-or-double-bladed-axe.   But I'm not sure where the idea of Hyrcanian Cavalry using the sagaris comes from, Herodotus states in his Histories that the "Hyrcanians were armed like the Persians", which coincides with https://alexander-the-great.org/warfare/hyrcanian-cavalry ("they typically used light armor, spears, and bows"), but maybe I've just not found the source from where this comes from. On the other hand (if a name different from "Scythian" wants to be used for some unit), Herodotus mentions that the Saka (closely related to the Scythians) did use the sagaris: "The Scaran (sic) Scythians had about their heads caps which were carried up to a point and set upright and stiff; and they wore trousers, and carried native bows and daggers, and besides this axes of the kind called sagaris. These were called Amyrgian Sacans, being in fact Scythians; for the Persians call all the Scythians Sacans".   And, something interesting that some could have noticed in my first link: many representations show these warriors being women, the idea being that the Amazons were inspired by mounted female Scythian (and Saka, among others) warriors. According to Diodoros Siculus, "at that time the Sacae were ruled by a woman named Zarina, who was devoted to warfare and was in daring and efficiency by far the foremost of the women of the Sacae. Now this people, in general, have courageous women who share with their husbands the dangers of war". The archaeological evidence seems to support the existence of Scythian (and similar) female warriors, I think this being one of the clearest cases to increase their representation in this respect (if this has not been mentioned already in the 15 pages of this topic that indeed I have not read).

We need a toggle so everyone's score can be seen in-game like in AOE games. 

An interesting gamemode would be Score Victory, ie when a player reaches a certain score, or else when everyone resigns whoever has the highest score wins (the latter for MP games that need to be cut short). Presets could be 1000, 2000, 5000, 10000, 50000, 100000, etc. This mode would force players to focus on a healthy economy, and could even lead to pascifist games that's only goal is to reach the score first. After playing quite a few Multiplayer matches, I have found that this would be a useful, and interesting, victory condition. ATM the score for players at the end is basically useless, since score is irrelevant to whether you win or lose in all existing victory modes, and sometimes while playing MP I don't have time to finish a match, or ended up with a draw game, and one of us had to resign (creating an unfair win), whereas with the score victory, or even as a fallback alternative to when a player resigns, we could have seen who won.
