Its always interesting to see the exact point in which a post changes to another unrelated subject.
I prefer this system, in fact I'd like it if Institutions would spread more globally through trade or something after a point.
For the record I hope the reason Tribal Federations are getting this treatement is that the rest of the Tribal governments are getting some attention (I would love a Mesoamerican region with governments that were slightly historically accurate in the future rather than not at all as it is right now).
To talk about historical accuracy in the early game or in the set dates is one thing, but to talk about it in the late game is kind of... yeah, unless I skipped the part in history class about Vikings invading Europe in the name of Odin or Ming sticking around until the Industrial revolution, I think its kind of a moot point.
And its not like the whole European tech advantage at this point in history holds that much merit either, people often talk about "European tech" as if it was universally Britain-in-the-Victorian-era levels from 1600 onwards and everyone else was in the stone age or something, the reality is that much of Europe was agricultural and dependant on artesanal guilds and manufacturies, like the rest of the world, that was one of the driving forces behind the fall of Metternich and the 1848 revolutions after all, Great Britain-level technology was the exception rather than the norm up until the tail end decades of the 19th century, much of their gains were due to the political instability most of the world found itself at that time rather than exceptional technology most of the time.
And its not like Great Britain was in some kind of technological singularity either, India and China were more productive in terms of both quantity and quality, to give you an example according to wikipedia, the Bengal province alone was producing somewhere in the neighborhood of 2,232,500 tons of shipbuilding while the entire British Empire's amounted to 340,000 tons, and this only really began to change at the end of the century for decidedly political reasons, even then, with how unstable the continent was, I should remind you, the British went bankrupt invading India, like actual insolubility broken, and that was just a few years after the african Ashanti Empire defeated them during the Second Anglo-Ashanti war (the first one was kind of a draw after the British brought in local allied troops), the industiralisation didnt turn the British into a technologically superior country at the flip of a coin, rather their Empire was built on political manuever ----> that resulted in economic gain ----> which THEN fueled the technological edge they would gain (for a few short decades) at the END of the 19th century, NOT the other way around, or so I think.
... jeez, I really should learn to make shorter arguments.
