- 字幕依据：What would the world look like if Hitler never lost? Let’s get specific: what if Britain failed to fight off the Nazis alone? What if Japan invaded, but not Pearl Harbor? What would happen if Hitler made a completely different set of choices during WWII instead of the ones that eventually led to his downfall?
F9U-C61jw30@0:00 - 字幕依据：France’s fall was not enough to force the hand of its greatest potential partner–the United States–whose divisive domestic politics and distance from the European continent still render it a remote friend-in-waiting. Back across the Channel, Adolf Hitler congratulates his generals on their brilliant tactical victory.
F9U-C61jw30@1:10 - 字幕依据：Today, it’s hard for us to imagine the Second World War ending any other way than how it actually did–with the Allied powers pooling their military might against a common enemy, overcoming steep odds, and achieving their goal of unconditional surrender.
F9U-C61jw30@2:26 - 字幕依据：With France divided into a German-occupied northern zone and a collaborationist Vichy southern zone, the United Kingdom, its Dominions, and its imperial colonies braced themselves for the long, solitary fight ahead. In all this, the greatest question remained: How would Hitler’s forces capitalize on their hard-earned gains in Europe?
F9U-C61jw30@3:49 - 字幕依据：Scores of transport vessels are strafed in the crippling attack which destroys several vital dock facilities in the process. Immediately turning to the airfields and radar facilities, Goering and Hitler sensibly encourage their pilots to bypass cities altogether, avoiding one of their biggest strategic blunders by focusing wholly on military targets.
F9U-C61jw30@6:30 - 字幕依据：buildings, medicine, food, wine, weapons, armor, and more. The team behind Myth of Empires tried to create a realistic combat experience, allowing you to fight using 18 types of weapons and armor, as well as many siege weapons and horses, which results in massive, immersive battles!
NGFI2kQpk5g@1:32 - 字幕依据：Unfortunately, Calimmachus’ library catalog is one of the texts from the library that were lost. As significant as they were, the Pinakes were far from the most useful or extravagant texts that were lost. Eratosthenes, who was the head librarian in Alexandria, accomplished one of the greatest feats of ancient times.
NGFI2kQpk5g@4:13 - 字幕依据：Euclid of Alexandria is considered to be one of the greatest mathematicians of all times and his Elements remains one of the most published books to this day. With such a legacy that he had left behind, it is inconceivable how much of his research was actually lost.
