Hello Everybody!

Today is a Special Day!
One year ago, on the eleventh hour of the eleventh day of the eleventh month, the first version of the Open Beta of The Great War was released! In less than a week, we reached 30.000 Subscribers and 50.000 Subscribers in three weeks! Three months after, we had 100.000 Subscribers.

In December, Mod DB awarded us the 3rd Place in its popular contest of Mod of the Year 2016 and now a year later, all our expectations have been largely exceeded. To date you are more than 200.000 to have donwloaded and played our Mod on Steam. It's amazing, again Thank you very much all for your Support! It still means a lot for us.

To Celebrate this Anniversary, we just have released the Open Beta 0.5 of Hearts of Iron IV: The Great War!
You can download it on Mod DB or on Steam.

As always, with or without Paid DLC, your gaming experience on The Great War will be very similar.

Among the changes in this new version, we have new Interwar Events, new National Focuses, new Treaty and so on. All the adding features, changes are in the Changelog available here: Steamcommunity.com

We'd like to thank all the contributors who joined us when we put the Mod on GitHub but also to all the translations teams! Bit by bit, the Mod grew each day and became what it is today!

On a final note, as you may know, The Great War has always been developped freely and on our free time. As everybody in daily life, we have many obligations that require us to spend more time on it and less on the Mod. Nevertheless we will still keep The Great War compatible with Hearts of Iron IV over time and improve it as musch as we can.

Happy Birthday The Great War! See you soon for more upcoming projects!

Another idea for the Brest-Litovsk treaty: The event could include a choice for Germany to release Poland as a puppet: IRL, the Germans didn't recognize any Polish claim in the treaty, which was later used as an argument to justify the Treaty of Versailles' harsh demands. So the two choices could be: 1, Germany releases occupied Polish cores as a Polish State/Kingdom puppet, with either a president or (probably a Hohenzollern) king. 2, Germany refuses, Danzig and Pozen become Polish cores.

Frankfurt treaty still leaves the countries at war. It can be prevented by making Austria-Hungary white-peacing then annexing Serbia in the event instead of puppeting them (then maybe puppet-release them as a separate event?). There should be a decrease in world tension in both scripted treaties, so the losing countries won't form another faction immediately. (not fix, just an idea: It could also spark communist/fascist civil wars and country releases among the losers, as it happened with the central powers in real life.)

A great mod and I'd give it a 10 if it was finished. It's still technically is a 10, but some miner issues need to be worked around.
