They were Spanish men, often pulled from Spanish colonial forces, who led expeditions in the name of Spain. Yes, they may have been messy affairs and not always legal, but it's not as if all the nobles of Europe were passive and loyal. Especially given the sheer distance and logistical issues involved in governing those lands what unfolded in the aftermath was hardly unthinkable. As I said, things like spies and diplomats could certainly be viewed as part of the conquest of the New World, but that's assuming that the process isn't simplified to dropping off a regiment and being done with it.
You're ignoring the point though. Spain, the nation, was deeply involved in what happened. The King, the homeland, and the government may not have had much involvement, but that doesn't make these events any less "Spanish". The game gives us full control over these events and as such they need to be designed and balanced in a way that represents the actual effort of the forces involved.
Who is arguing that the Barbary pirates would have fallen if not for the New World? No one is saying this. It's been suggested that if Spain wants to focus on conquering North Africa, it's going to be a big diversion from the New World. Similarly, colonizing the New World would be a big diversion from North Africa. The idea is that expansion and consolidation are limited.
See my previous comment.
I think it would be absolutely ridiculous to have an event which automatically annexes a country for you with no effort. It would be one thing if it gave a conquistador and/or a CB, but it's another thing to just auto-annex someone for no reason.
The New World was both a resource and an end. Yes, much wealth was siphoned off to fund ventures in Europe, but many wars were fought over the colonies themselves and the trade routes in the New World. Additionally, populations in the New World grew rapidly, making colonies a legitimate part of each respective empire. Things like administration and colonial protection become serious matters. Spain spent a lot of time, money, and effort on holding its colonial empire together. Despite a much different process of expansion and consolidation, colonial possessions were a resource just like any piece of land in Europe.
Hurt isn't what matters. What matters is the capability of Spain to administer a large North African empire while simultaneously colonizing and conquering the New World. Even if the New World was only positive for them (which it wasn't at first or in the long run), the question still remains as to whether they would have devoted as much time and effort to those endeavors if they had been bogged down in crusades and conversions in North Africa.
1. But for the nation as a whole it wasn't difficult which I think you conceded by your agreeing it was easy for the homeland. Every colony struggled to succeed at first. However in EU3 terms all the Spanish did was send a spy; a powerful and gifted spy but a spy nonetheless. Spies don't simulate men in back alleys stalking nobles; they include the incite nationalists/patriots (I know that sounds familiar to you from Cortez). For Conquistadores this was extremely difficult; as was the act of exploring the Ocean Sea by Columbus, which is even easier in EU3 then conquest of the Aztecs.
2. the overwhelming majority of those forces were natives; it was still part Spanish and wouldn't have happened without Spain, and Spain was the beneficiary but a simulation lets say of allowing 5000 Spaniards; don't they win? I have in OSC kept vast native forces at bay with 2000 infantry and 1000 cavalry (who were then trounced by other europeans) allowing a simulation of the numbers involved just seems to give Spain a 100% victory; is that really a better way to portray it?
3. Spain concentrated as much on North Africa as it's resources would allow; that didn't actually change at all; Spain was devoted to the Crusades and even sent a relief force to save the Knights. Ideologically Spain had a Christianizing; not civilizing mission and unlike the more race based colonial goals the Spanish won (Mexico is almost everyone a descendant of mixed race and catholic for example).
4. You do have control over it; the event is if you make a decision the ai (or if you are the Aztecs you) get a counter event where they make a decision lets give an example. "Cortez has encountered multiple factions in the New World he
A. offers a treaty of alliance and trade with the most powerful
B. tries to ally with weaker factions to conquer the new world
C. stays at Vera Cruz and yells at the governor giving you a headach"
If you press B the ai gets an event
"the strange but advanced people from across the sea have joined our enemies we
A. Throw everything we have at them (50% chance of victory ending the chain)
B. Invite them to Tenotchiclan we could kill them there if we have to
C. Do nothing; lets hope the coalition falls apart"
Lets say both pick B (historical so far)
"Cortez has arrived we
A. Sacrifice everyone who enters when night falls; don't give them a chance to get to know the city let alone return
B. Keep Faith
C. Submit to any demand he gives including religious"
If the AI follows the historical choices which it usually will Spain takes the Aztecs down, if it doesn't as you see they survive and get a chance to thrive which they don't under the current system.Their survival as AI will be unusual but possible.
5. The wars were fought because of the value of those resources; Santo Domingo produced most of europes sugar but they weren't the end game itself. Spain of course had to defend it's resources against enemies; but those enemies had european based ambitions. The French and British generally setup their own colonies which Spain easily prevented during the 17th century (see French Colonization of Florida).
6. Spain could have administered areas of the area close to home that it conquered; it's problem was getting the conquest. This should be simulated by making NA as powerful as it was historically. Of course if the ai or player mismanages those forces and fails to focus enough on technology that should go away but the way eu3 had determinism force 100% defeat for NA was even more outlandish then the 100% defeat for the Aztecs because unlike the Aztecs NA thrived through the 17th century until it's stagnation and decline in the 18th.
