IBM machines were used to tabulate the census used to track the Jewish people in Germany before the war and during the Holocaust, they tracked and counted everything happening in the concentration camps on IBM punch cards.
Look how far computer systems have come. Now Israel used an AI system and cell phone tracking to try to wipe out entire families.
A group of friends and I played a few years back and we found the natural end was when we could survive the hardest of the blood moons in our base without having any damages or breakthroughs and could easily beat any of the areas that were supply runs. We also had built multiple vehicles so we would bomb through in a convoy to wherever we were going and clear everything.
That was the end because we didn’t want to play anymore.
