I will look up that game. It sounds interesting. I hope nuclear war never happens. It would be a waste of human life. I do remember watching Carl Sagan Cosmos series. In one of the episodes he said that Planet Earth has a 99% chance of blowing itself up. I have never forgotten what he said. It was alarming to say the least. Hopefully we are on track to be one of the 1% who does not.
He made a follow-up a few years ago. Pretty good but has a heavy liberal bias, to the point of not being as "good" as the first one.
