I still think it is better to have the Manchu changed to “Oirat”. Both Kalmyks (employed by Russians) and Dzungars (who had their own “gunpowder Khanate”) are Oirats. Thus, the Russians, Chinese, and Persians (in case it is implemented in the future) could all hire Oirats as mercenaries.
Noted. That was a mental math mistake. However, I still suspect that even with 3 pop, Flamethrowers will be underused. The problem is that most artillery can one-shot them, which is an issue given that Flamethrowers have a very short range. Either the devs need to remove their infantry tag, or they need to gain siege resistance to survive at least two direct artillery shots.
I think most people are fine with stereotypes and playing fast and loose with history. However, players have problems when the game has significant anachronism (Song dynasty Flamethrowers), outright invent units (Meteor Hammer cavalry, some of the Native American rosters as I have heard), or have illogical artefacts (Qing cannot recruit Manchu to fight, new village/colony building wonders from the homeland).
For the Germans, I actually have issues about how they were not split into Austria and Prussia, especially given that the Americans and British (and Spain and Mexican) are both in the game as separate civs. While Austrians (HRE → Austria → Austro-Hungary) and Prussians (Teutonic Order → Prussia → Germany) are both Germans, within the timeframe of the game, the two states have very different lineages. Stereotype-wise, the Prussians were known for their disciplined line infantry, grenadier, and the Totenkopf Hussar. The Austrians are known for the hardiness of their frontier units (Grenzers, Hungarian Hussar, Tyrolean Jager), while the Whitecoats (line infantry) were under rather conservative (slow to act) leadership. Frankly there is more than enough information to split the Germans into two civs.
I am actually supportive of adding the Poles (Polish-Lithuania). The only problem is that they sort of disappeared as a distinct and sovereign state halfway through the game’s timeframe (through the Partition of Poland). But if the Aztec and Incas are included in the game, then the Poles are also justified.
The Confederate State (the US one, I am assuming) probably cannot be added as a full civ, since it lasted only a few years. However, they could be implemented as a US revolution.
