What stands against a campaign that starts with Czarist Russia in 1914? It could cover the whole WW1 against Germany and Austria-Hungaria. The campaign could either end in 1917 or transition somehow into the October Revolution. In that case it would be ideal if the Czar could somehow avoid or suppress the revolution and the entente could win WW1 in the East.
A very complex extension of the available campaigns, but should this not be possible either as a mod, addon or sequel?
