I avoid gamey expansions like that because realistically that would be impossible and silly, plus its most likely you don't have enough troops to cover the front in expansions like that. But, its still impressive.
I have built a few empires, my most famous being Italy- Grabbed the Balkans, Most of Southern Russia, Turkey, Half of France, Spain, Portugal, all of Africa(That can be crossed), The Arabic nations, Persia/Afagn, Switzerland and Luxemburg(Paradrop
). I didn't consider it gamey because I could cover all the land and the British/Soviets were fighting me every step of the way
. I eventually couldn't go farther into India/ Russia because of supply lines, and the Royal Navy/USN was still a powerful force so I stopped it there. Sorry I don't have a picture, it was 3.06 Beta.
