Another important quote, from the Steam page:
“In this inaugural chapter of a multipart saga,”
So yes, clearly more to come. But it also seems to indicate that this is historically the earliest of them. This DLC spans a century, the 5th. And who comes in the 4th century…
I think we can put a strong likelihood on the next chapter focusing on Alexander the Great, meaning Macedonians are a shoe-in if this is the trajectory of travel.
The original mod had the Seleucids as a separate civ, so they are a potential candidate. Other possible ones are Egyptians and Mauryans. Especially likely with the latter, as they fought the Seleucids. Persians, Spartans and Athenians were also part of the picture of this story, but with them already included, it makes things easier.
Jumping forward to the 3rd Century and the major conflict of the time is between Carthage and the Roman Republic, another perfect setting and a perfect pair of candidates. The AoE1 campaign for Hannibal wasn’t all that impressive, perhaps second time’s the charm…
Second century hasn’t really got the long campaigns that earlier centuries are centered around. But the century after…the death of the Roman Republic and the rise of the Roman Empire. I can’t see this being missed, and is a good opportunity to include the Egyptians, considering the massive part they play. Some Gaul/Germani/Briton civ is possible as well to represent the forces Julius Caesar fought.
So my prediction:
Chronicles 2: Alexander
Macedonians, Seleucids, Mauryans
Chronicles 3: Rise of Rome
Carthaginians, Roman Republic, ???
Chronicles 4: Caesar
Roman Empire, Egyptians, a Gaulic civ of some sort
