I have a distinct memory that I have mentioned Kriegsspiel before, but I'm not sure so here we go.
A friend recommended a video about the subject, and it was so good I wanted to share it with you all.
The video will explain it all in detail, but let me give you a bit of a teaser. Kriegsspiel or wargame in German, was a way to simulate battles on a table before actually fighting them in real life. Countries that adopted Kriegsspiel saw a marked increase in success on the battlefield compared to those who believed they didn't need such nonsense.
In time, civilians got into it, and thanks to that, we eventually got things like Dungeons & Dragons, the Total War games, Warhammer and much much more. Kriegsspiel even in a sense invented hit points. A huge portion of modern gaming came from generals trying to rehearse battles in advance.
I highly recommend this video if you've ever played any of the games I mentioned or indeed anything even remotely similar, or if you just like history.
That's that and all that. Join me again next time and until then, have a great week!
