I remember my father teaching me lots of things about submarines playing this game. He said, when the war boats is on top of you, you got to stay quiet. They will circle around trying to find you, but it is your job to keep your head cool and wait them out.
This game is probably the main reason I like submarine movies so much. I love getting all my information about submarines confirmed. The small things, like "Torpedo in the water!" or when the Americans can hear Red October because of the Russian's are singing.
I recently learned that this is one of Sid Meier's first games, submarine simulation. I think it is very good, and I really love the excitement when you have Japanese destroyers on top of you, trying to pin down your location.
