For the Communist Ending, I think you missed a golden opportunity to use the song "L'Internationale" as the background music. For the Nazi world and German Empire world I think you should have made Panzerlied the background music for the Nazi world instead of Preussens Gloria, and and for the German Empire world it would be more suiting for the background music to be Preussens Gloria Nonetheless, I enjoyed the video.
For me, the only Good Ending was a world without Cold War. Which means, I prefer both United States of America and the Union of Soviet Socialist Republics to teach some sort of ideological understand. If both US and the USSR wanted to be superpower, they must work together. Not rival against each other that causes a proxy wars on other countries.
Good ending is more True ending cause it is the ending where we are but it could have been better And the ultimate good ending sounds like a nightmare, now the whole world is a bunch of extremely obese politic extremists who make school shooting and no public health care, so the poor provinces are now struggling to survive a simple flu
