Still don’t think CP victory is possible against competent Allied play.
UK sends whatever is needed to block CP victory until US forces arrive in strength = game over.
RR needs to generate “Red” (i.e. Bolshevik pro-CP) forces in Russia to fight remaining “Whites” and Allies. Also produces free German/Austrian units to represent released POWs.
Germany needs a second production centre closer to the Western Front, otherwise too many CP units spend early turns in transit rather than fighting. Otherwise allow u/l rail movement between controlled tts.
USA does not build units or collect income until actually at war. Then it gets one “draft” turn to buy cheap (half price) infantry only. This represents the fact that until 1917 the US did not intend getting involved, so did not spend more than was usual on the military.
Victory conditions based on “political collapse” are unworkable since the war will generally always be fought on allied soil. Instead it needs to be a formula based on CPs must control X victory cities by turn Y in order to win.
