STOCKHOLM - 07 February 2019 - The great democracies of the world face unprecedented challenges on their legitimacy. Fascists and Communists pressure freedom loving nations on every side.

Please note that the game version sold to people in Germany is slightly different from the version sold elsewhere. See the link below for information.
Please note that most likely any new threads on the subject of the German version will be locked. (Due to the fact all threads on the topic inevitably derail)

In light of some criticism towards me in particular, I feel I need to clarify a few things:
- Do not create multiple threads on the same topic
- Do not flame or insult other users or developers
- The more constructive and civilized you are, the more we will listen to your concerns.
Posts/Threads violating the 2 first points will be locked or deleted without hesitation.
If you have feedback on how you think we could do things better, or how the game could be better, then we are happy to listen. Just typing out various profanities without any constructive points serves no purpose to anyone (besides possibly the person writing it, needing to vent)
TL;DR I hope this makes sense. We do not intend to "censor critique", but we will remove stuff that is causing nothing but provocation, without adding anything to a normal discussion.
Thank you! Read more
Hello!
We aim to post a development diary around noon (Stockholm time) every Wednesday where we aim to keep you guys updated with what we are currently working on.
Development Diary Archives[www.hoi4wiki.com]
For information, questions or discussions: Please go to our official forum thread[forum.paradoxplaza.com]
The purpose of these videos is to make short and easy to find guides on specific topics. Once the game is released we expect a ton of user made let's plays and tutorials. Since these tend to be quite long, and it might be hard to find the specific thing you have questions about, We made these. I like to call them wiki articles in video format.
