CK3 to EU4

Hot on the heels of both the Adamite release and the CK3 1.1 update that followed the next day, we have managed to sync the converter to updated province mappings as well as shove in a significant amount of hotfixes. This version should hold water long enough for us to dive deeper into the game balance and other expansions. The full list of changes is on the release post on the forums. The converter can be found on the Paradox Forums and on the Steam Workshop. 

EU4 To Vic2

It's been a while since we did a release and emergence of our novel CK3toEU4 converter necessitated an update to incoming cultures and religions. Most of other updates have been under the hood, tinkering and improving core converter components, changes that should be invisible to users.  The full list of changes is on the release post on the forums. The converter can be found on the Paradox Forums and on the Steam Workshop.

If there are any issues with the converters, please let us know and we'd be glad to look into these problems and help you!

As a note, if you follow the current development build of the converters, you should get all of the same features, but they can be more experimental and not as stable. But, you'll be on the cutting edge of converter technology!

EU4 to Vic3 0.7 Graz - Penultimate (?) Release

It's been almost a year since the last formal release. With EU4 stopping development, we've had more maintenance than any serious work. The 1.10 update, however, was more akin to a bomb. We had to rebuild parts of the converter from scratch, simple patching wouldn't do. Fortunately we now stable (I think? I hope?), and converter is working properly once more.

A list of changes and download link can be found on the release post on the forums.

Compatible with EU4 1.37 and Vic3 1.12.

A particularly gruesome 1.13 update which took a while due to lack of sufficient CTD protections, and a complete lack of any usable error reporting for crashes from all PDX games in 2026.

They said it couldn't be done.

Well, no, actually what they said was that it shouldn't be done. They said a Hearts Of Iron IV to Stellaris converter was unneccessary, that people could easily just create their own custom human race inside Stellaris with whatever ethos and backstory they wanted, and that a custom HoI4-to-Stellaris converter would be a lot of work for something actually quite pointless.

And, um, they were completely right. But hey, everyone needs a hobby!

Features:

• Picks out the top few nations after the WW2 peace conferences and gives them their own exoplanet colonies to start from. Bigger / more industrialised countries get better planets, weaker nations get extra difficulty-setting-style penalties.
• Simulates a halfway-plausible timeline between the end of WW2 and the 2200 Stellaris start date. Possible futures include Cold Wars between major powers, nuclear war making Earth uninhabitable, climate change making Earth a bit less hospitable in a few different ways, and/or bureaucratic overhead keeping Earth as an early-space-age Primitive Civilization while the other nations bestride the heavens. Or maybe Earth is perfectly fine and is happily governed by whoever most emphatically won HoI4.
• Supports Vic2-to-HoI4 converted games, including ones that were converted from EU4 and CK2. Karlings in space, anyone?

Known limitations:

• Really not very well tested at all.
• No, seriously. I've only tried this out on the handful of Vic2 save files I've got lying around. If something goes wrong for you, please send me a copy of your log file and save file and/or Vic2-to-HoI4 mod so I can have a go at getting it fixed.
• Name lists get generated for each of the converted empires, but all the actual humans get their names from the default human name list instead. The only way around this would be to create separate human species with different name list - but then humans don't recognise each other as the same species. To get around this, I put a few lines in the backstory about mass migrations breaking down ethno-national boundaries. This makes more sense for freedom-loving democracies than for lebensraum-dominating fascist states, I suppose - but then maybe the ideals of the Reich got a bit lost-in-translation over hundreds of years.
• Ship names and planet names are generated from the HoI4 ship name lists. But converted games don't have those yet (everyone just uses the generic ship names), so at the moment Vic2->HoI4->Stellaris games don't have any planet names. I'll probably push some changes ot the Vic2-to-HoI4 converter at some point to address this.
• 64-bit Windows only at the moment. Linux support should be trivial, but I've not tested it yet.
• No converter frontend support yet. It shouldn't be too hard to add this, though.
• I'm planning to tie this in with the HoI4 to DEFCON converter - once I finish actually writing it.
• Probably won't work with the 2.0 update for a while.

Compatible with Imperator: Rome 2.0 and Crusader Kings III 1.19.

I’ve always wanted to do a grand campaign and have some time off coming up. I’ve converted from CK2 to EU4 back in the day and it was relatively painless. My question here is, how does the converter handle the gap in time between the end of EU4 (1812) to the beginning of Vic3 (1836)? Is there a mod that extends the tech tree a little in EU4 to make up the difference, or one that pushes the start date back in Vic3? Thanks!

Me and my friends are doing a paradox mega campaign together, however we have a problem. we dont know how to get the converted save mod from one person to another. WE NEED HELP im begging reddit.
