Even I registered for this sweet discussion, here we go. Yes, separation of Russian culture causes Homeric laughter from a historical perspective, but if you play Paradox games long enough you can understand that EU4 moving to controlled sandbox type of games, there is no about history at all. Realize that first. And second, they cant know about everything, The guys are well versed in Western history and project processes occurring in Western cultures in the far east, not realizing (and we can not blame them) that the development of cultures and subcultures completely ceases to work in Russia since 1200+ (I mean the territory, Russia those days did not exist), because when you killed more than 100 years by Tartars cultural diversification can not take place physically, takes place exclusively the union, just to survive.
This things very clear for us as russians, but this is game and rules for everybody is same.
Prerry sure that guys from India or China or Japan can find mistakes in ther own ingame region, but this game is just too big to do unique mechanics for everybody.
