my main issue with tech is simply that once the europeans hit 1500 or so, only the ottoman military can fight them. I had a game as morocco a while back, got north africa tried to push into iberia. I had 3 quality if iremember right and example. Battle of where-ever, 20000(me) v 13000 (dastardly spanish), me 14000 casaulties, them 6000 and i had the better general too. Annoying how inferoir the rest of the worlds army get. Maybe make generals influence army preformance more than baseline soldier stats? Also id think if you were fighting a european nation that had better tech than you, you'd tech up ridicolously fast(maybe increase the land tech bonus if you're fighting a westernized nation).
Then there is the issue of nations transporting 15000 soldiers across oceans at 1500 but thats for another 90 page or so long thread
edit: and then there is poor poland and hungary.....
well, tech has to influence european vs european significantly, so no wonder that Europe vs rest is a steamroll.
It is an issue of scaling, more than anything else. The only way to make Europe vs Europe not just a number decide everything, while the Europe vs world not a steamroll is to make scaling nonlinear.
Can be made by kind-of-sort-of thing, that if one side has more than X (say 5) levels of tech advantage, it will get the malus, let`s call it tactic&equipment mismatch malus, so having more than X levels of tech advantage is less impactfull per level than first X tech level disadvantage.
How are Poland&Hungary poor? They are perfectly capable with good innovation slider. Then, either vesternisation, or PU, or partition by countries that westernised at right time.
Following the collapse of the Mongol Empire, the plagues and famines, and the failures of the crusading movements, most of Europe rolled back from its development in the High Middle Ages. Contact and trade with the East became increasingly hard and more often through middlemen. Population and output decline drastically, resulting in economic and social consequences as well. Europe was left fairly isolated, devastated, and unstable. The developments we normally associate with the Renaissance era, namely the evolution of gunpowder weapons, the emergence of long distance trade and colonization, and the influx of knowledge from new lands, all work against that setback. They all also have parallels in earlier societies outside of Europe. Thus to reflect these developments relative to each other, it makes some sense to bring Europe into the Renaissance era at the beginning of the game, because, as you said, it was largely catching up in most respects and eventually would push ahead by the Enlightenment.
Mongols are conected how exactly?
Trade with east always was thrugh middle man.
How exactly did the plague rolled back scolars, and other advances taken from east during crusades?
How exactly did the agregation of wealth in hands of the remaining nobles hurt?
What you say is absolutely incorect. Europe was not left any more isolated. Just because the Ottomans got controll over middle east.
It is true that renessiance would have happen in 13th century if not for plague, but plague did not roll back anything, it just delayed things.
Plague did not roll back knowlege. Plague did not roll back social structure, in fact it advanced it.
