I've been having a VERY interesting game. Started in 1936 in the original game as Germany...no mods or cheats...and things changed IMMEDIATELY. For one thing, Germany has been democratic since June 1937. WWII started when the Soviet Union invaded Poland. Germany was neutral in the beginning which allowed me to build up a HUGE army and found my own faction that includes the United States, Romania, Belgium, Turkey, Portugal, Ireland, and others. Well, by 1943, Germany was ready to go to war. The Soviets were fighting Allied forces pushing into Central Asia through British Raj and into China, and after three years of nothing in occupied Poland (I had won Danzig peacefully prior to that) they left their front lightly defended. Despite that the first few weeks of the war went poorly. The Soviets struck north towards Danzig and reached the city itself, but the arrival of Norwegian, Danish, Belgian, and Swedish troops turned the tide. After that it was a VERY slow slog into the Soviet Union itself, reaching Moscow by the end of the year (The Finns took Leningrad) and pushing the Soviets to surrender by April 1944.
The war continues elsewhere though. The Allies are now fighting against the Italian Republic-led Novus Imperium Romanum, which includes Japan and its possessions as well. The war in Asia is just picking up after a primarily naval war. Germany...after its Pyrrhic victory in Russia...is resting before marching into Hungary and joining the war.
