I remember a game being played in the crewroom of the premier maritime sqn at ISK back in the 80s. Started around 1000 and was still going strong when I had to leave for the sim (1300) so I handed over to another co-pilot. Returned from the sim at 1600 to find same game still going (playing for hacks as BEagle says adds a much better dimension) to find only one of the original players still in the game
Sad to see the tradition dying out - it really was a good team building morale inducing sport!
