The Mongols have four unique Ranged Cavalry units: the Nomad (II), Steppe Nomad (III), Horde (IV), and Golden Horde (V). Their listed benefit is that “they’re particularly effective against enemy Light Infantry” and “effective against enemy Musket Infantry”. The game confers these advantages by giving all four units a +60% damage bonus against Light Infantry and a +45% damage bonus against Gunpowder Infantry.
In reality this ends up being a really weird bonus to have. Not only do they still normally lose in fights against those units, but those same units are supposed to be counters to Ranged Cavalry, making these bonuses unintuitive for both the attacker and the defender.
Quoting Wikipedia, “the Ship of Theseus is a thought experiment about whether an object that has had all of its original components replaced remains the same object.” The PC of Theseus is a system that had almost all of its components replaced, and we just gave it another round of upgrades to dial the existentialism up even further.
I previously posted about fight control in Rise of Nations, and briefly mentioned how the conventional wisdom regarding Age V combat (which I had also subscribed to until briefly before writing that article) was misguided. Age V combat is not “Age IV combat but with more guns” — it’s actually fundamentally different.
