WWII began when germany used the AP to DoW Poland. Poland had a defensive pact with France and England. Germany then bribed Russia to attack Poland, which they did. Then Germany used a tank rush to defeat France. Germany didn't have any coastal cities, so they couldn't build transports. They had to wait until France came out of rebellion, so they sent their bombers to start reducing England's cultural defenses. Meanwhile, England rushbuilt tons of battleships and destroyers and parked them around france, so Germany couldn't send out the transports.
So then Germany decided to attack Russia for whatever reason, and sent their tanks to Moscow. But Russia had switched to Nationalism a while back and started mass drafting infantry, and building tanks. Eventually, when German forces reached Stalingrad, they didn't have enough siege and all died. So then Russia unleashed a massive SoD and started pwning Germany.
Meanwhile, Japan was at war with China, and decided to DoW America. Japan bribed Germany to DoW America, and they did. So then America rushbuilt tons and tons of tanks. battleships, and carriers, and destroyed Japan's naval SoD. Then America used Marines to attack the Japanese by sea and go ALL YOUR BASE ARE BELONG TO US. Meanwhile, America sent transports full of tanks to Africa, and with the help of England, they both started pwning Italy, who had troops with only 1 XP. But then they met the Afrika Korps, who had all the combat promotions, and they had to use Tanks as siege, because they were playing with the old patch. Eventually, they recaptured Egypt.
So then they invaded Italy, and with their Great Generals Patton and Montgomery, they were able to move really fast, and captured Rome.
Germany then sent another mini-SoD to try and capture Rome, but failed.
And then England, America, and England's vassals used English based bombers to bomb France to weaken the units there and used marines to capture cities along the coast. While Russia advanced west, they started moving east, and Germany's SoD was split so much, they couldn't stop the Allies and then Berlin was captured and they lost.
