For me the magic of sh3 is to create the aspects of submarine war like how you imagine how it works or based of what someone knows about this.
To breakin the enigma or to do supplies missions, mining or mapping, plotting the course of the submarine with real navigation and of course to approaching enemy calculate his course and speed and attacking. that kind of loneliness magnetize me to this sim with the great work of the modders appreciated.
