Very well, let's take a look.
For the base game, I think I'll work with 20 civs + 1 preorder bonus one.
Not many newcomers at the starting point - I imagine for the base game to sell, it'll have to introduce an expected base of staples that most people desire to see. If there is innovation, it's going to be mostly among leaders.
Arabia - I imagine a design focused on the golden age of Islam, which leads us to the Abbasid Caliphate. Umayyads I'd rather save for a potential Moorish Civ. A religious-commercial, scientific-commercial or religious-scientific design should suit Arabia, though I suppose the last of the named options is kinda what Civ VI does, so I'd rather pick one of the other two named. I don't know Abbasid Caliphs closely, so I suppose a return of
Harun al-Rashid is something I can live with - especially since he's appeared only once in Civ so far.
Babylon - We can't miss an ancient Mesopotamian civilisation. I guess they will be scientific the next time, too, but I can hope they add a bit of a builder flavour into the ability mix. For their leader, I wouldn't mind seeing
Nabopolassar, but I would also be content with the return of
Nabuchadnezzar II. Perhaps with him, we could get some nice builder ability - he is known for massive building projects in the city od Babylon. Hopefully, if he gets chosen, he'll crawl out of the cave he sat in in Civ V...
Benin - A newcomer from the Western African coast. I can't tell you much more - I am not that well acquainted with the region's history, but I'd love to learn through the game. I suppose queen
Idia could work.
China - Methinks reusing leaders for a civilisation as ancient as China is a humongous waste. Thousands upon thousands years of history, numerous imperial dynasties, yet so little leader variety across the games. So I say preemptive no to the return of Wu, Kublai and Qin. And absolute no to Mao. I'll be slightly more lenient towards Yongle here - the next game could still lean into his encyclopedia or his treasure voyages and make abiliities out of those, so his return with such a new flavour I wouldn't mind. But, generally speaking, I'd still prefer a new leader altogether over him. And a new dynasty, too. To fulfil that, I suppose we have three major choices here - Han, Song and Qing. I'll be honest, I know almost nothing about the Han Dynasty. Only the fact that it's considered the golden age of China. I'll be happy to learn should Firaxis go with a Han leader and flavour, but considering my current lack of knowledge, it's hard for me to get excited about them. With Qing I am more knowledgeable, and I wouldn't necessarily mind seeing them. They have some interesting leader options - namely Kangxi and Qianlong (I suppose one could also go with Cixi for a big name and a female leader, though I am not particualrly fond of going with her, considering the disastrous era she presided over). I suppose a Qing design might end up being a bit militaristic though, and it's not exactly my preferred design here. This makes Song flavour the one I would like to see the most. From what I've read, it feels like a fascinating era offering a lot of potential for designs. A well-rounded populous empire playing similarly to current Yongle, or perhaps a civ leaning a bit more into being a scientific-commercial power... No leader recommendation on my side here though - I don't know any Song emperor well enough to pick here.
Egypt - My knowledge of Ancient Egyptian history is fairly surface, I don't know many Pharaohs, let alone closely. I'd prefer seeing another leader after three consecutive games with Ramesses II, and I'd rather it not have a Ptolemaic Pharaoh. I would kinda like to see a return of queen
Hatshepsut. A design centered around her reign could make Egypt into a fun economic-monument builder hybrid civ (a playstyle right up my alley!). Should we go with a previously unseen leader though, I wouldn't mind seeing what they can do with
Ahmose I. Or they can try
Thutmose III to give Egypt an interesting militaristic twist.
England - I'd be perfectly content if
Elizabeth I found her way into Civ VII, too. A naval-cultural hybrid design would come with that, I suppose. But if we are to go with a newcomer leader, I'd be interested in king
Henry V... And I must admit, reading this thread did spark some interest in me regarding queen
Anne.
France - I would like to see
Cardinal Richelieu leading France, leaning into spying and diplomacy. If we're to lean into a bit more straightforward militaristic approach and want to avoid Napoleon (though I'm not one of the folks saying preemptive no to him), I can propose king
Philippe Auguste. He has the nice advantage of coming with medieval French design - and I would absolutely love to see a depiction of a king draped in a magnificent blue robe with golden lilies. And as third possibility, I am going to unironically present the option of
Napoleon III. The man has left behind stunning infrastructural work in France, which is a bit unfairly forgotten in face of his foolish adventure in Mexico and ultimate defeat by the Prussians. I imagine an ability besed off the renovation of Paris he ordered could lead to interesting results.
Germany - While I'm generally for trying out some fresh things, here, I am going to be conservative and will say that a return of
Otto von Bismarck is fine by me, because a) I am not particularly fond of using Holy Roman Emperors for Germany (except maybe some earlier ones - Barbarossa was an okay choice by me), and b) I love the industrial era. With him, I picture an industrial-military German design. Boring, uninspired, but effective.
Greece - I like the city state league design they went with in Civ VI. I say we ditch Alexander and go with this again. If they can keep the design grounded, without overuse of cringey references of
300 (I suppose I'll survive it if they make such a reference in the game's achievements, I guess), I am not against the usage of king
Leonidas of Sparta as such a city state leader. If they can't do that, I'd rather turn to Athenian leadership under, say,
Themistocles or
Solon. But I'm also willing to accept
Philip II of Macedon to lead a united Greece.
Inca - The Civ VI Incan design was pretty good. Due to it though, I can't come up with a design that would stray from it. As such, I'll only suggest a leader. I suppose after two consecutive Pachacutis, we can get
Huayna Capac for Civ VII.
Japan - I am partial to Emperor
Meiji, with whom Japan can become an adaptive industrial beast. I am however also perfectly willing to accept a daimyo or shogun - but I don't know any notable ones outside of the ones I know from Civ (and outside of Toyotomi Hideyoshi) to propose. As a side note for alternate design from Meiji's Empire - Tokugawa's isolantionism in Civ VI is a nice design, I wouldn't mind a repeat of that.
Mauryas - I believe the time has come for the Indian blob to perish and be split. I picture a threefold split into the Mughals, Mauryas and Cholas. Three Indian realms, different in religion and in time they existed in at their peak. With the Mauryas, we'll be receiving the most "standard" depiction of historical India - war elephants and all that - and so they get into base game. A return of emperor
Ashoka could be nice, but I wouldn't be too upset if we see
Chandragupta Maurya for the second time instead. I imagine a military-religious design could work.
Maya - My knowledge of the Maya is very surface, so I'm not going to propose any design here. I don't know any Maya leaders outside of those introduced to us in Civ, so I'm not proposing anyone, either.
Native North American Civ -
NOT THE CIV IV BLOB - READ FURTHER! - I'll be brutally honest here - Native Americans are on the very periphery of my historical interest. I recognise a need of them in the games, and I'm all for giving them space both in the base game and in the expansion packs, but I simply can't get myself to be excited about them, and I am more or less apathetic towards which peoples we end with in in this field. Pick whichever native people you'd like to see here. If I were forced to pick some, I suppose I'd say the Iroquois.
Ottoman Empire - Three (or four?) consecutive Suleimans warrant a bit of a change, but I suppose keeping the Ottoman Empire an expansionist one is fine. The empire existed for over six centuries and had several notable sultans, so I imagine a return to Mehmed II isn't necessary, though I wouldn't particularly object to him either - we haven't seen him for two games, and his greatest achievement - the fall of Constantinople - transformed into an ability could be interesting. The guns of Orban as a unique unit could be fun to see, too. But the primary candidate for militaristic Ottomans on my mind was
Selim I, who in brief eight years of his reign tripled the extent of the empire. An alternate design, leaning a bit into culture, could be interesting, too. For such a design, I believe
Ahmed III and the Tulip period would be the perfect choice. And if Japan and France weren't telling enough, I am in love with the 19th Century, and I think the Ottomans have something to offer here, too. I feel like
Mahmud II designed around the disbandment of the Janissaries or
Abdülmecid I with a design focused on the Tanzimat could provide some interesting gameplay opportunities - but I suppose those two are only realistic as emergency options in case no other great industrial era reformer gets included.
Parthia - We can't be left without a expansionist cavalry-heavy realm, and the Parthians seems like a good choice for that role. I don't know their rulers well enough to choose among them though.
Rome - As a law student (from a country that built its legal system upon the principles of civil law) that went through Roman civil law in the first year as a mandatory part of my studies, I must state that Roman law is an immensely fascinating aspect of the Roman society, and what is even more impressive - it's largely timeless. You'd be surprised how much the law in civil code countries builds upon the foundations left to us by the Romans! But enough about my little legal gushing - I concede that won't make exactly a fun ability
. So instead, I imagine the Roman design for Civ VII to be something similar to the one from Civ VI - a moderately expansionist infrastructure-building realm. I don't particularly care whether we end up with Rome portrayed as the republic or as the empire, but I don't know many republican leaders, so I'll only propose some emperors. I can stomach a return of
Augustus, though I wouldn't necessarily mind a new emperor, either. I am partial to
Marcus Aurelius and
Diocletian as potential new faces - and if I were to pick from the two, I'd probably choose the latter. I have a thing for reformers.
Russia - I imagine the recent unfortunate events in Ukraine might make the representation of Russia in the form the Romanov Russian Empire a bit undesirable at the moment, considering that it was Romanovs who historically conquered the area. Though I had some relatively harmless designs for the Tsars Alexander I and Alexander II on my mind, I'll let them go for now. The current situation is naturally a no to Soviet representation as well (though it would have been a no for me nevertheless even if no war was going on). I imagine the Grand Duchy of Muscovy or Rurikid Tsardom of Russia representation should be okay instead. It would be a breath of fresh air, too. Great leaders to pick from that period would be Grand Duke
Ivan III or Tsar
Ivan IV.
Siam - I picture a Siamese civ under king
Narai. I believe he could be an interesting choice with abilities leaning towards diplomacy. However, I won't shut up about my love of the industrial age yet, and apart from him, I'm also going to propose
Rama IV or
Rama V. One paved the way for the country's modernisation, the other conducted it brilliantly and saved Siam from ending colonised. If I were to pick one of the two, I suppose I would be leaning towards Rama V.
United States - I don't really have any designs to propose here. I can more or less accept anything, from the newly-independent States with an exploration-settling focus, to the rising power of the industrial age with a builder focus, to the modern superpower era, which can work with more or less any abilities - scientific, cultural, you name it. I lean slightly towards the second named design, but, you know it by now, that's just my industrial era bias. Anyway, outside of that, I have no particular leader preference.
Preorder:
Denmark - The inevitable viking civ. The vikings don't interest me at all, but I guess they can't be omitted. I suppose the preorder bonus civ should be big enough name to motivate the players to make the preorder purchase, and I think the vikings should work just fine for that purpose. King
Cnut should do as their leader.
The post is long enough as it is, so ideas for DLCs and expansion packs I'll save for potential later posts.
