Form Commonwealth with base game

[Migdalin]

I have the PU with Lithuania and have fully integrated Mazovia. The mission to form the Commonwealth still isn't firing, and makes it look like I have to directly own most of Lithuania as Poland. Do I just need to wait and be patient, or is this another "you must buy DLC 22 to do that"? Like, in the base game, do they expect me to break the PU, then conquer and annex most of Lithuania if I want the Commonwealth?

You can form Commonwealth as Poland or Lithuania with the base game. That's what I have and I've done it with both. Both countries need admin tech level 10 to form Commonwealth. However, Poland and Lithuania have different requirements after that. Mr Wiki has all the details.

What are you talking about? Can you show some screenshots? Are you playing with mods? In the unmodded game there is no mission which forms the commonwealth. On the contrary, there is a mission called "The Commonwealth" which you can complete after you formed the commonwealth.

Waiting is not going to accomplish anything. You should have two decisions which allow you to form the commonwealth in different ways. Their tooltips tell you what you need to do to enact them.

Dont you need Danzig to form the Commonwealth?

Okay. I'm still at tech level 4. What I see in the game is that I have one green checkmark for "complete Reincorpporate Mazovia," and four red checkmarks for "All provinces in the XYZ: Owned by Poland." When I hover over the question mark, it highlights provinces that are all in Lithuania.

But the Wiki does say that admin tech level 10 is required - something that didn't show up in the new AI-powered Google searches. The Wiki also calls out four provinces that I need to have cores for, two of which (Danzig and Marlenburg) can't be located using Find. So: shrug.

The names of Danzig and Marlenburg might have changed when I took them from the Teutonic Order? I remember seeing Danzig mentioned at one point, but it's nowhere to be found now.

If you annexed the whole Order, then you do have both provinzes. Danzig should be called Gdanks now and Marienburg i dont know but is right next to Danzig.

Just read the decision description. Conditions should be required provinces and Lithuania's either owned by you or non-tributary subjects. That's your clue.

In which year are you? If you already integrated Mazovia, but still have tech 4, you are likely far behind in tech.

This sound like you are looking at the mission "The Commonwealth" which has nothing to do with the requirements to form the commonwealth.

Using AI to answer eu4 questions is a very bad idea. Many AIs operate on old snapshots of the internet. And even if they have a recent snapshot of the internet, they can't determine for which eu4 version that information is(in contrast humans can look at the date of the post/comment/video and compare it to the eu4 version history to see for which version it was written). And the AI can't really draw conclusions from the things which it reads. It can only reliably answer questions which have been answered thousands of times before. But most eu4 questions are not like that.

The wiki usually lists province IDs as well, you can enter them into the ingame search to find the province no matter how it is called.

Aha. Yeah, I was looking at the mission, not the decision.

AI is very, very bad at providing accurate information on topics this specific and obscure. In most cases it will either provide badly outdated information, highly generalized information that doesn't actually answer the question you were asking, or failing that it will simply "hallucinate" information, aka making ♥♥♥♥ up and feeding you completely false info.

And yes, the provinces of Danzig and Marienburg do get renamed to "Gdansk" and "Malbork" respectively when owned by a nation of Polish culture. If you've taken the state of West Prussia (no need to even fully annex the entire Teutons), have a PU over Lithuania, and haven't lost any of your starting territory, you should have everything you need to form the Commonwealth without further conquest, unless you feed Lithuania with too many additional provinces and render them ineligible to be integrated via the diplomatic decision. As mentioned above, the Commonwealth is not formed via a mission, but in the Decisions tab; there you should find two separate PLC formation decisions, one via conquest and owning Lithuania's provinces directly, the other via PU'ing Lithuania as you have done. Both decisions also have Administrative tech 10 as a requirement, although if I'm not mistaken one of the missions available in the Lions of the North DLC can reduce this tech requirement from 10 to 8 when completed.

Please note research AI operate along the same principles as game AI. Their advantage is that they can collect a crap load of data in a hurry. There weaknesses are that they are really not very good a sorting and collating the information they have found without a lot of human input and that human input can be subject to the biases of the human providing said input. AIs do not think in the same way as do human beings

I'm not sure what you mean by "research AI", but the large language models like chatGPT work nothing like the AIs in computer games like eu4. The AI in eu4 is mostly a bunch of hardcoded rules like "if X do Y" or it uses scripted ai_will_do values which take a base factor and either multiply or add a bunch of conditional factors for each possible option and then pick the option with the biggest result(sometimes with some randomness where bigger factors give a higher chance) or it acts completely random(e.g. many event choices) or it does some hardcoded cost/benefit analysis(sometimes with scripted weights or preferences).

They do not "think" at all. They aren't even actually "AI's", they're just branded as such to build up hype around them despite the relative lack of advancement there has really been. All that LLM's do is analyze raw data for patterns and attempt to mimic those patterns, usually with laughable or disastrous results. They're not even that far off from 10-year-old projects like Cleverbot, just with a shinier coat of paint slapped on and way more processing power (that uses as much energy per year as a million average households) behind the scenes.
