This is in part due to the AI development problem I'll go into, but the code needs to be optimized. It feels like many balance changes have been big swings back and forth, breaking the game. The past few years for EU4 have been extremely rocky balance wise. There's just so much going wrong here And it's not based on difficulty but tedium and enduring these stupid bugs every single game. Then when you conquer certain land, some tribes have 100 devestation which makes the land pretty much unworkable for decades or you waste monarch power to buy it down. 60+ day diplomatic times for 50,000 different tribes I want to annex Oh wait, they formed a federation and now there's land 500 miles away that's not connected.

Then I have to deal with naval attrition trying to transport my troops over multiple times as efficiently as possible. When I played as a native, all the countries in my federation got deleted and I was left with one province. Them STEALING your land when they form a federation. No, what I have a problem with is the sheer amount of bugs, federations forming another federation that cause stupid HRE style bordergore. The numbers look huge but they're so backward in tech with their heads cut off sieging random provinces. With all it's shenanigans that make it extremely tedious. I don't even bother colonizing North America anymore. But FoW is the most obvious one because it's so blatant/consistent that player can use its cheat vision against it fairly reliably. There are a few others that creep into gameplay time to time, such as NA/SA colonial nations sustaining a blockade on Crete or Indonesia. But there is no question about the difference in FoW rules for player vs AI.

The AI is stupid, so this is not enough to defeat experienced players. This is not mere "remember where the unit was/is", it knows precise location and move orders given with only a chance to forget it per unit time. I've used the movement of troops in my territory to intentionally scare it into lifting siege (before it was modified to be a bit more sticky with sieges), repeatedly, to move-cycle it out of ever sieging the fort using troops it couldn't see.

I've seen it react in an instant to direction changes by armies chasing it in the fog when running around in player territory. Excepting "lucky nations", I guess those get freebies. This is true, unless you increase difficulty (in which case you should expect it/would be strange to complain). But maybe if siege times were reasonable, this would be less of an issue (though it would also imply that fort spam is even weaker). I'm not convinced this is healthy for the game. AI is less able to snowball, less able to put up a fight.but simply takes longer. Slower wars with less units per opponent seems like the worst of both worlds to me. I'm also still not convinced the AI "should" build forts to the extent that it does, because it is sacrificing a non-trivial amount of its ability to make units in doing so. It would be a help, length of battles and sieges are both unrealistic and cancerous to gameplay right now. Not in the way described, but it's objectively true that the AI does cheat. PDX had to dumb down the entire combat system to aid the AI because it cannot understand reinforcing or building proper army compositions and positioning its armies correctly. It can't even differentiate between death wars and when it should lightly help an ally. Last time I checked, AI isn't willing to (or even capable of building an economy that can) go massively over Force Limit and hard commit to wars, the same way a player can. And again if you seriously have a problem with AI temporarily seeing into Fog of War to simulate a player having basic object permanence, then that's simply a "skill issue."

There is no learning AI in this game, its just a set of weighted numbers and a dice roll. That's "cheating" as much as it is cheating when the AI sends a successful diplomatic action, or chooses to send an army to a fort. AI "cheats" Fog of War? The AI can "remember" where troops are by seeing slightly into FoW after a unit enters it. The AI is notoriously bad at the game vs any decent human player. If you seriously cannot keep up with AI developing all provinces to 20+ and staying on tech, building buildings, then I don't know what to say other than "skill issue," as blunt as that is. Click to expand.The AI does not "cheat" by genning resources.
