What mod are you using again?
Rise of Mankind 2.92 with A New Dawn 1.74B
A lot of different units, and I heard you mention a limit on how many units can occupy a square. Is that your own units, or all units? (Can you block off a choke if you have enough units there?)
It's based on team. Originally, it was altogether but that lead to tons of problems where it was impossible to attack a "full" square. So, you and your ally could both have 5 units on a tile if the limit is 5 but it rarely happens like that.
Yes, you can block off a choke hold during a war and it works pretty well.
Anyway, sounds like a beast of war. That sounds like fun. Don't always want it to be too easy, after all. Will you defeat Spain by force of arms, or by another method...?
The newest version of the mod actually gives me another method. It's expensive Espionage Points wise however. Basically, the idea was to put all 100 of my EPs into Spain and then camp spies in ALL their cities and then Arm Rebels in ALL their cities. The problem? 5000 EP each.
The mod makes spy missions scale to game speed so on Eternity Speed (4500 turns), the "Spread Anarchy" mission causes
38 turns of Anarchy while unhappiness and unhealthy missions also scale but they don't tell you they do in the tool tip.
Late game missions include turning off the power grid of a city (highly devastating given the nature of the mod in the far future) and Planting Nukes which is super expensive. I believe 40k EPs give or take a few thousand after bonuses and stuff.
------
To give you how powerful Aid Rebels are, using it on the fringes on an empire WILL cause that city to revolt. Problem is is that I never produced enough EPs to do it continent wide. I was going to do that to Korea but Inciting Revolt which, scaled to game speed, is 3 turns of disorder in the city, allowed me to push into Pusan and Nampo without siege units on flat terrain that highly favored my ultra Teutonic Knights.
Seoul is a fortress city now. The mod allows the player to use Expanded Castles which means besides the 125% defensive modifiers, there are also special buildings such as murder holes, castle keep, and ballastria which gives a 50% bonus to archery units and 25% to archery units.
Wosan, however, did not benefit. I didn't bother building all that in that city even though its on the border. As a matter of fact, none of my mainland cities have such a powerful defense like Seoul. I'm planning on improving Toledo and the Khmer Capital (name escapes me) since the former has my only source of horses and the latter splits Siam in half.
-----------------
Anyway, I'm getting off-topic. If I go to war with Spain, it will be a LONG war. Especially with 6 units per tile. I could simply storm in Madrid if I wanted too but it would be a bloody siege regardless. I would have to allies to call in. Rome hates me. The Ottomans are cautious and have a different state religion. I haven't meet the Russians yet but know where they are thanks to Spanish maps and it looks like they may have some experienced troops after seeing that they have conquered the Americans a long time ago.
And no reason to bring up Siam. I had to make sure that the war against Spain ended fast with me taking Valencia or Toledo OR else Spain would try to get Siam to redeclare which would mean me having to back out of Toledo. That's the scary thing about the mod's Ruthless AI option. The AI, when it declares war, will bring in war allies if it can.
So, the way I'm looking at it, to actually invade Spain, I would have to build up the largest fleet ever seen to make sure I can strike Madrid, the Incans, Babylonians, Romans (just in case since they don't like me) and Spain's Mayan holdings and that's
still not overwhelming enough. I tried to look at Japan during WW2 for tips which is why when I invaded Korea, I struck in Pusan and Nampo at once by sea.
Now I have caravels and caravels have 9 strength compared to the 6 of triremes and 5 of Siege ships. Problem is is that Spain also has them and landing troops in Madrid will require even more escorts despite the short swim (movement of 3 vs movement of 5 of caravels+1 since Spain discovered the world is round).
So yeah, I'm thinking of it from a "real world" standpoint I've taken while doing Realpolitik England. The invasion would require dozens of galleys, nearly a hundred combat troops if I want to overwhelm them quickly, and dozens of more escort ships plus even MORE ships to blockade Spanish ports.
In Realpolitik terms....hundreds of ships and probably a few hundred thousand men dying before it was all over.
Then again, Spain would have the same problem trying to invade Germany. Siam? Siam is roughly the same strength as Spain and I but I share a land border. However, I am
not going to march south onto Paris. Never. Tundra damages troops and Paris is landlocked and not worth the fighting.
No more wars. Not for a very long time but if I can, I plan on trying a massive spy ring to incite revolution across Siam. If I take Siam, then I can turn all arrows/ships/swords northwest on Spain.
.....Just noticed the irony of Germany having to deal with two fronts in my game. In theory, Spain and I should be best friends. We even had a Free Trade Agreement which is why the German Butcher's Guild was so big in Spain. Yet, Spain and I have had two wars by now, both started by Spain
at Friendly. The first time was so half-hearted I don't even talk about it but this one was clearly a victory for me.
------------
It's basically like the (awesome) Starcraft 2 commercial narrations.
"War is coming in all its glory."
Edit: I should probably explain my end game if I'm losing in the late game. In vanilla BTS, if I ever ever ever ever ever ever (and so on) lose my capital for any reason, I'll simply nuke everything and I do mean everything and everybody. Usually with enough nukes and guided missiles to level every city on a standard-sized map and in one particularity BAD game I had, on a Huge map. Why? Rage-nuking>rage-quitting. But in this mod?
ICBMs, atomic bombers, hydrogen bombs, the "Peacemaker" ultra-nuke which has a 32x32 radius basically making it a continent buster and that's the mild stuff compared to the Biological Weapon line of weapon which, at its worst with the Plague Bringer, can potentially spread across the planet and the fusion weapons that vaporize entire cities in a single shot or in the case of a Fusion Nova, a city and the surrounding countryside.
It can get pretty nasty. Luckily, it's never came up to such a degree. The Peacemaker is bloody expensive and if our England in the Realpolitik game ever got one, we could take out all of North America or Africa. I should probably test that now that I brought it up. On a Giant Earth Map, it could probably still take out a good chunk of Asia leaving nothing but irradiated cities and 1024 tiles to be scrubbed of fallout which, given that most of the workers are killed during the single strike and multiple civilizations are hit, could take the rest of the game to scrub completely even though it would be an international effort at that point. Can't forget that someone using Peacemakers would probably have Plague Bringers.
