75 years ago today the UK declared war on Germany, 25 years and a month after the First World War. The Second World War is mythologised in popular culture like no other:
“I sometimes think the second world war has changed our entire western civilisation’s view of war, because, of all the wars in history, the second world war is closest to fantasy war, in which there is a dark lord, whose guys are actually evil and dress in black and wear skulls on their uniforms. The first world war was a much more typical war: what were all those people really fighting for?”
George R.R. Martin
“Nazis. I hate these guys.”
There are RPGs about the horror of the front lines, the suffering of resistance fighters, alternate histories, an entire GURPS line for thorough historical analysis, and lots of opportunities to punch out Hitler.
