My idea from an earlier thread.
"There is nothing wrong with those outside of Europe keeping up (relatively) well until the 1700's. After all, that's kind of what happened. What needs to happen if we wish to "model" history properly is a drop off around this point when the agricultural revolution in Europe really kicked off and enabled a surplus of manpower combined with advanced banking and investment techniques derived from trading investments/missions on the part of proto-capitalists in the Netherlands and Great Britain that allowed Europe to run away from the rest technologically. And you know what? Most Asian/Islamic World nations actually do start lagging rather significantly in the 18th century in my games so, from my limited point of view, this seems like a good balance. Not perfect, but it works. Because honestly there is crazy amounts of Westernization.
The best way to model this (imo ofc)? Do what I listed above. Have advancements in Banking and Infrastructure be derived from having extensive trading influence, a more advanced form of government to distance from feudal/medieval tax collection methods, relative cultural homogeneity, and a much higher development to province ratio to represent how an expansionist empire like the Ottomans empire would have difficulties with this sort of advancement would then enable them to invest in further internal improvements like a proper Academy of Sciences or "nudge" them slowly to a proper scientific revolution. Anyone who accomplishes this should be able to "modernize" and experience and exponential growth in tech advancement. It just so happens that these things rather favor Western Europeans due to their position to easily influence trade and the HRE and large number of Great Powers in the area ensuring (hopefully) that the province to development ratio stays high. If this is implemented properly then honestly we could do away with tech groups all together, simply giving Europeans the tech advantage to mil that they get during the religious wars should be sufficient to represent their increasing skill at waging warfare. And the religious wars themselves should be expanded to include things like the French Wars of Religion, the expulsion of Puritans from England, and all those other fun things.
In fact the reformation itself should provide a rather substantial tech discount to those that convert due to the proliferation of bibles and how everyone in Northern and Central Germany all of a sudden started reading due to the importance of the personal interpretation of the Bible and the spread of the printing press (another possible way to give Westerners a tech reduction without making "groups"). The Counter Reformation should provide a MATCHING tech discount as it was an intellectual refutation of the arguments of the Reformation while still making some concessions and led to the development of perhaps the most venerable collection of intellectuals formed by any institution ever under the Jesuits. Seriously, these guys were basically intellectual missionaries that got people to convert by proving how smart they are.
TLDR Get rid of tech groups and have dynamic events and mechanics instituted that allow anyone to modernize but still favor Europeans."
Questions/further suggestions:
1)What do you think?
2)Maybe have a continuously changing "Innovativeness" counter/bar that when it reaches 100 have a scientific revolution start? And this revolution increases tech rate exponentially?
3)Tie the Dutch and English Governments and/or advanced government forms to this counter/tech discount?
4)Have a country with the scientific revolution for 50-75+ years trigger an industrial revolution giving some really nifty bonuses but several unique disasters?
