The mod has been in development since 2016.

The Great War allows players to start the game in 1910. To make this possible, the creators have prepared a wealth of new content, such as units, technologies, characters, flags, sounds, and events. We also get a new map and many gameplay mechanic changes. Although the project is still only at version 0.25, it is already fully playable and can easily provide at least several dozen hours of enjoyable gameplay.

The mod’s update is all the more welcome because its creators are currently also working on their own commercial grand strategy game, Fields of History: The Great War. The authors recently announced that they have partnered with MicroProse, which will publish the title and financially support the project. It’s good to see that, despite this, the developers have not abandoned their modification.
