The CP has the oppertunity to spread the fight out, to keep the British occupied elsewhere other than supporting France. And with so many diffrent powers each game could be different. Can Austria-Hungary manage to hold off Russia one turn (say you get really good dice rolls on AH1) and thus allow Germany to put greater pressure on France?
And also you forgot the Balkans campaign (though I guess that’s kind of #3), in the end this little known front was a major contribution to actually ending the war, it completely broke the Ottomans and AH Empire once they broke through the Bulgarians, and the fact that they would have to again fight a two front war (3 if Romania joined in again) convinced the Germans they were screwed.
And How long will the Ottomans be able to hold off the British? Or will the British forgo the old Porte in order to concentrate on Germany?
It will indeed be interesting. I for one will lead Glorious Russia to glorious victory…or glorious defeat.
