That ending... ooofff. Central Powers were clearly winning too. They just made a second breakthrough in France and were apparently conquering subsaharan Africa after seizing Egypt (and crucially capturing the Suez Canal). Collapse of France looked inevitable.
I'm guessing a soviet victory before I watch the video, because germany has more research slots at the start then the Soviets, and that bonus is cancelled,
with that bonus, AI almost never wins as Germany. With both Russia and Germany max tech, it's a simple numbers game. Germany would be crushed inevitably. You could see it when Germany lost more manpower than Russia and that makes it a matter of time only.
