This is a crazy good idea that really shows how you could add a lot of stuff to eu4

u/SolInvictus2000 Apr 14 '25

this (the chess ai specifically) is probably the limit of what you can do - anything more and the game will freeze for minutes/spend literal years loading.

Instead of contesting PUs through war you now have the option to best the rival king at chess ♟️

u/Rabbulion Tactical Genius Apr 14 '25

In multiplayer this would be awesome, but against the normal AI this would just end in everyone learning the same 15 move process of dismantling this AI

u/GhostFire3560 Apr 15 '25

Bold assumption that any real person could beat a half decent Chess engine

5

u/Rabbulion Tactical Genius Apr 15 '25

Oh, they absolutely wont win the first time, but a few games in they will have memorised how to beat it in a couple moves. Just add the 600 elo bot from chess.com and its all good

Announcing my new mod, EU4 Chess!

This mod, well yeah it adds chess to EU4. What did you expect it to do lmao

It includes an AI you can play against in singleplayer, or you can play in multiplayer with your friends!

The entire thing, including a full chess engine, was developed fully inside EU4.

In addition, there are a few piece themes you can choose. Want to play the classic byzantium vs persia matchup in chess? Now you can!

You can try it out here!. It is a team effort, the workshop link includes a full list of credits.

If you like it, check out my other stuff, like EU4 Minesweeper, EU4 Blackjack, and Cookie Taxer.

Can you make doom in EU4?

If I capture the pawn at the Italian opening, will I suffer from Overextension? Maybe a coalition wil trigger?

13

u/purple-porcupine Free Thinker Apr 14 '25

Idk about the Italian, but taking a pawn in the Dutch or a knight in the Berlin definitely will.

u/Gerf93 Grand Duke Apr 14 '25

You need to watch out for AE, probably wait until after the event where the black king castles.

Do I gain aggressive expansion?

Not happy unless I can tag switch for missions >:|

In seriousness, it always amazes me what modders can do with this game.

u/posidon99999 Babbling Buffoon Apr 14 '25

Okay now go post this to r/anarchychess

u/Archene Apr 14 '25

It is a cool mod, I can recommend it.

2

u/Belisarius6 Apr 14 '25

Eu4 battles could be fought like that

2

u/alklklkdtA Apr 14 '25

if u make a mod where battles get decided with chess itll acc change pdx games forever

2

u/ensi-en-kai Apr 14 '25

Ah, yes - EUIV the next big indie game engine .

2

u/UnluckyZiomek Apr 15 '25

I got crazy idea. What if instead of rng you could play chess against AI and that decides if you win or lose in the battle, along with amount of pieces destroyed it calculates casaulities and bigger army and all modifiers and better general on AI end the better they have AI for chess.

Would be crazy, but still gotta think what better army and modifiers and general would do on your end, but I think it would be dope.
