Good question really.
I do recall I got a book on submarines from my Aunt and Uncle when I was a young lad, good book too, explained about sonar and active sonar, SINS and the like.
Played Silent Service on the NES when I was about the same age too, but oddly my interest always seemed to drift more towards modern submarines, especially after reading the abridged version of To Kill the Potemkin. Then got Fast Attack for the PC and watched Hunt for Red October, and after that was Sub Command and Subsim.
What do I like about it?
The stalking mainly. I'm not fussed if I don't fire weapons at all, but stalking an enemy submarine, getting a good solution without it detecting you in return. That's good fun.
