We can agree depending on what that depth and accuracy was.
In the end EU is a game about Europe rising to dominance, and thats what (i would dare to say) most expect from it.
That doesnt mean that places outside of Europe cant get more detail, like new mechanics (factions for example), more events, more decisions, more provinces and tags, more unification paths etc. But IMO it does mean those countries cant play by exact same rules as Europeans (same tech rate, same unit quality etc) because that would not allow world to develop the way we expect it. And then theres the argument that many places (specially in Africa and Americas) were simply not on the same organizational level as most countries in Europe. Couple of Mongol states (tribal states by EU3 standards) didnt even have a writing system.
