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!

Ok that's very strange: I'm playing as Germany and had almost a hundred divisions fighting a Dunkirk-like pocket of American and Japanese divisions in Italy. They had almost 7 divisions, but they sound as strong as, maybe, 3 Soviet Unions? Or 5 Nazi Germanies? lol Even with this massive numbers I've lost almost 1M manpower trying to defeat and I'm actually loosing the offensive.
Other thing I think is unbalanced: I've go to war, and as I'm defeating the Russians, in the West I could barely defeat Luxembourg and did not advanced a single mile after that. After I defeated Russia I pulled in the troops on the other front to help in France and Italy. With 90 more divisions, and plus 100 divisions from Austria, I was incapable to advance even a mile in the two fronts. I have 110 divisions fighting 40 on the border with Belgium, and nothing happened (!!!). I got so furious of it, that I turned to France, Belgium and Italy and deleted many of their divisions. But, surprisingly, a week later they appeared with A HUNDRED more divisions. I think even if you deploy your lines before completing training it is almost impossible!
I'm doing something wrong here?

Are the Alllies too strong or Germany too weak in this mod? I've put more than two hundred divisions on the European front and my power can't even hold a candle to THE RUSSIANS

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.
