Petrov Day
A Petrov Day ritual for two groups at once, say two cities: each side has one missile, a warning window, and false alarms that look exactly like real launches.
Arkhipov Day
The same game for Arkhipov Day, 27 October: the day in 1962 when Vasili Arkhipov refused to launch a submarine's nuclear torpedo.
