Yeah big thing that got me was how close the nazi's got to a complete european empire. Not a united one but if given a few decades of not or poorly challenged nazi rule maybe a united Europe would of happened.

And a proper, united, (not some weird EU thing) Europe doesn't sound bad. It would be slightly bigger than the US and double the population. Just imagine what could be done with all those resources and people. For the majority of people (white, and with nazi eugenics what they consider "perfect" europeans.) I think life would improve in many ways.

That being said overall nazi rule would probably be bad if history is teaching me facts. Suppression of free speech, "supreme" race nonsense, genocide, etc.

On a side note I don't see Man in the high Castles idea of a conquested America realistic. It relies on the nazi's getting the nuke first (If I recall correctly) and America either surrendering or failing to defend in a main land invasion. (I don't know which because I only watched one episode a long time ago. Would watch more but I'm forgetful.
