D Day

Hello Everybody!

It's been now two years since the release of Hearts of Iron IV, Happy Birthday Paradox!
This day, is also the Anniversary of the D-Day, and we do not forget that there’s a graveyard in northern France where all the dead boys from D-Day are buried.

For this event, we've just released a new update, The Great War Mod Open Beta 0.5.3

As usual, to have a better view about the changes, a complete Changelog is available here:
Steamcommunity.com

To be noted that, as always, with or without Paid DLC, your gaming experience on The Great War will be very similar.
If you want to contribute to this great project, discuss, share your ideas, it's time to join us on GitHub: Github.com

why the war start date is 1915
i don't want talk for the October revolution that is starting in 1915 too that was in the previas version too the same problem

and i have tried 5 times to play and 4/5 Itali join the central powers
i don't want to tell you what happens next the whole world was Looney well not that much like one time the whole world was communist and i was the only one. There was nobody else like me or democratic

plus kebab empire (ottoman) miss 2-3 time to enter the second balkan war and not like he was in research mod i let him do the focus tree just in like 15-17 days just so he can enter but he is like No not interested

i'm sorry if this is a bit rude but yeah i'm blaming paradox not you who is trying to keep the mod up to date with the patches

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.
