I'm still on my Inca game, kinda want to get further in before moving to the new DLC. Plus gotta wait for MEIOU and a few submods to update anyway, and it allows time for balancing and people to dive into the mod before I get into it
With that...
I have now colonized 99% of all south america's coastline. Holland (which turned into a vassal of his, but don't remember what it was renamed to) has a tiny part of it (just three provinces in southern tip). I colonized around it, blocking him from going further in. And besides those three provinces, Holland completely stopped colonizing. I also have a fort (just the first basic one) in every other province along the eastern coast of South America and going to the south tip. Also a really good fort in Panama (which I upgrade to the best I can get). A couple other coastal provinces have a higher level fort as well, otherwise I mostly stuck with the cheap one.
I also have troops lined pretty much all along the northern, eastern and southern part of South America. So once war comes, not only can they not land troops easily, they have to deal with all my troops. And they can also respond easily when the enemy is landing his forces.
England is still a good ally, he got a really good military leader so his military tech is really good. He keeps feeding provinces to Canada, which has a high liberty desire. Too far north for me to interfere lol.
Spain still hates me, and he also hasn't colonized at all in ages. I think I "broke" Spain by kicking him out of the Americas
He isn't even colonizing Africa, he isn't really doing anything at all lol. For the past 50 years, he literally has done NOTHING lol. No wars, no expansions, no colonizing, nothing at all. Oh well...good for me
France is colonizing north Mexico into what would be Texas. France is actually doing some pretty heavy colonizing of North America, more than even England is. I plan to declare war on his colony once I get the rebellions under control (the Spanish colonies I took keep revolting). Which is looking to be kinda long-term problem I am dealing with. The unrest keeps being really high, even after beating rebels after rebels. I also would rather be able to build an actual invasion army (which I do have an okay sized invasion force sitting on my capital), and not use my defensive troops. But, France doesn't really pose much of a threat, and lost a war in Europe pretty recently in the game and white peaced a second. Plus England is rivals with France, and they'd join the war (I got favors, but they'd join anyway) and their military tech is 2 levels higher than France. France does have good allies (but England could still beat them) and could probably beat my navy. But he would lose his colonies since that is a long distance war, which I have the advantage of. And its not like he can really land in South America lol. Even Spain couldn't really defend his colonies that well and my forts weren't even setup then.
I kinda want to invade Europe at one point, but heh, I'll probably have moved onto the new DLC by then. Which, I plan to be Tunis. I only invaded Europe (as the american natives) once since I've played EU4 and that was as Aztecs and I never was able to get a foothold at all. Farthest I got was taking Ireland and then being slaughtered and sent back home
But no one could conquer any of the Americas either lol, and then a DLC came out and I moved on
At least I accomplished my goal of the current Inca game. Colonize all of the coastal region of South America, and put forts in every other province
Kinda a short game goal really, but I knew the DLC was coming out, so didn't want a huge long goal of conquering the world lol
The only problem with the strategy of forts all along the coast (and not really anywhere else) is if an invasion force broke through even one fort and defeat my initial forces protecting that region around the fort...they pretty much have free reign all the way to the capital
I know an actual player would take advantage of that, but its just the AI...so...
I do have a few forts around my capital though, but otherwise its pretty barren and open land. Not much troops to defend it either lol.
