I think that the events of the post-Great war are not included in the 1914 scenario...
Indeed, it would be great to have a very long campaign starting in 1914 (or, why not? even before, including russo-japanese war and balcanian wars) with all the events included.
That's (obviously) an enormous task for the modder(s) because it's necessary to foresee all the possible deviations from the real history. And are many...
Every single deviation from the "natural" course of the events has to trigger a series of other events, trying to mantain a convincing and plausible history.
The first big crossroad is the Great war.
Assuming the all the great powers decide to enter in war respecting the historic alliance, we can have three possible solutions:
1) Central Empire defeated = treaty of Versailles event and all the consequent flow of events (annihilation of Austria-Hungary and creation of states like Poland, Czekoslovakia, Hungary...). That's a problem. it's necessary an event that prevent France from invading Germany since occupation of Rhineland (it would be too simple for the player destroy all the tiny german forces of that time). An event should simulate the reluctance of the democracies to break out a war after the massacres of the Great war...
And the chain of events should consider the possibility that Russia isn't defeated by German and Austrian troop in the Great war, but gives her contribution to the final victory.... doing so, erase any possibilities for Lenin&Co to achieve the control of the government (first important deviation)... Perhaps is the event "great economic crisis of 1929" that provokes popular outbreak and removal of the Zar?
2) Central Powers win the war defeating the allied armies in France (event that trigger the possible end of the war, simulating the war tiredness of the population that push government at asking for peace). How imagine an alternative treaty of Versailles? Austria-Hungary will dissolve aniway under the pressure from the nationalist movement of hungary, czekoslovakia, croatia and so on? Then we can have fascism in Italy (liberal government dissolved by the defeat in the war) but allied with France in a revanche against austro-german for the liberation of the region occupied (at least alsace-lorraine for france, veneto-trentino-friuli for Italy)
3) stalemate: peace by impossibility of each alliance to achieve the victory. A result for that can be the development of nazism in Germany, fascism in Italy and communism in Russia under the pression of the populations, tired of the useless and expensive war... and so a series of event triggered that more or less reflect what really happende...
what do you think?
