As for me, both of my degrees are in history. I deliberately keep my style casual here though. I’m here for fun. Writing dissertations is not fun. Wouldn’t dream of dragging all my academic baggage here with me.
I like playing strategy games and world history and especially enjoy when the two overlap.
Now, more to the point of this thread, I expect all alternate leaders will do at least one of a couple of things, if not all.
A. Represent a different aspect of the civ, either a different dynasty or time period.
B. Provide a different play-style or differently-behaved leader.
C. Provide a fun new idea for the devs to experiment with.
Who do you think needs a new leader the most right now? I’m eyeing Egypt, China and Russia.
I would go even further and say that the leaders so far are intended to represent different polities that players have been wanting to see in the game for years. The Greek and India splits were some of the most popular mods on V steam mods, and William the Conqueror (and Eleanor of Aquitaine, to only a slightly lesser degree) were also fairly popular.
Going off of that, as well as other indicators such as the German city list, the odd Russian choice of the lavra, the Rome uniques, and odd polities/leaders representing Arabia and Egypt, my guesses are thus:
* Germany - Arminius. There are a lot of popular German mods, but somehow Arminius is really, really high. Obviously Bismarck isn't a mod, but Arminius is more popular than some 99% of other civs, period. Mechanically, could be a cultural/defensive leader.
* Russia - Olga. Russia also has a lot of popular mods. I believe Stalin is just a tad more popular than Yaroslav, but only by a hair. And like the Maurya and Sparta players have been clamoring for Kievan Rus', which I do not see being a separate civ within VI's current design. Olga works as a "Kievan" leader who is also undeniably Russian, and if you've noticed "wimple" leaders like Tamar and Eleanor have foregone the wimple for some reason..... Mechanically, could be a religious/military leader.
* Rome - Theodora. We've been over this up and down. While Byzantium could go either way, two pretty solid presumptions exist. One, that if Theodora is the leader as opposed to a later ruler, it really should just be called "Rome." And two, that if we have the Angevin Empire, the Mauryan Empire, and possibly others like Kievan Rus' and Magna Germania represented by alternate leaders, it would feel extremely weird if Byzantium were a separate civ. I, for the record, do not consider Macedon a "second Greece," so much as "Alexander's Alexandria," a pure cult of personality. Mechanically, could be religious/naval leader.
* Arabia - Several options have been listed. An Umayyad representative could be Atikah bin Yazid. Ibn Saud could be a modern Arabian leader. Makeda could be an ancient Arabian leader. Given how long and varied the Arabian legacy is, I expect at least one more leader, and if we ever get three leader civs, I consider it one of the strongest candidates alongside China, India, and France. These would all likely be cultural leaders because I don't see the devs going near Arabian military history.
* Egypt - probably Ramesses II. Cleo makes sense as an alt leader who was pushed up to sell the base game, but as with Catherine and Ghandhi we really need a more appropriate option. Military leader?
* China - I stand by Empress Cixi as being the frontrunner, to cover Manchurian China, as well as bookend Imperial China and represent the transition to the modern Chinese state. Likely a diplomatic leader that would combine well with China's turtling tendencies.
These are the six leaders that I feel the game by its very design beg to be added. Many of the other base game civs feel like they were designed with only one leader in mind. If "Spain" were representing "Hispania" and blobbed with Portugal, I would also include Isabella of Portugal (in fact I think that may have been the intention initially), but I think Portugal will be its own civ.
As for "third" leaders, I think Kublai Khan, Charlemagne, and Nur Jahan/Sembiyan Mahadevi could be third leaders. I would prefer Nur Jahan lead the Mughals in a separate civ and the third India leader be Chola, but I do recognize that corners will be cut, and that if we do not get a Mughal civ Nur Jahan could represent "India" in a pinch.
As for DLC alt leaders, I would rather not. I have seen interesting ideas proposed for Hungary, Poland, Scotland, Netherlands. But at this point I would rather we fill out the European map more than start doubling up on niche polities. I would rather have Ireland, Denmark, Bulgaria, Romania, Switzerland, Bohemia, even
Yugoslavia over Wenceslaus or Louis or James or William or whoever.
