While the kingdom of Nohr is supposed to be poor, the king and royal family shouldn't be. they literally own the country, and if it is based on medieval European countries, then it would have the royal family and especially knight, who basically had their own little countries with any rules they wanted, then the Nohr campaign would have much more money than it does. Also, in Birhtright's defense (How Ironic as how I was just trashing it) it actually is historically accurate. If you watched game theory's video on who would win, a Viking, knight, or samurai, MatPat found that the Samurai would win based solely on how much money medieval Japanese Samurai's were making, and how much more skillful their warriors were. No matter how well you fought (or how drunk you were) if the enemy had way better equipment, and had the ability to shoot someone as accurately on a horse as you were on the ground, like the Japanese, then you've basically lost the fight, explaining as well why Hoshido is way easier than Nohr (or maybe Nintendo wanted to give some props to Japan?). So, in short, Conquest is historically inaccurate in gameplay, and Birthright is surprisingly accurate compared to it. I won't even mention Revelation (Oops I did it anyway) as there is no such thing as magic floating cities and invisible warriors unless you've been smoking some bad dragon herbs, so, you can't make an accuracy estimate based on it. The link to said mentioned GT video earlier is Here.
