Sure you can play a sub sim game, but could you name and learn what every valve, every gauge, every duty station is in this picture of the USS Drum control room, plus be able to operate it in case your shipmate was injured or incapable of manning his duty station?
Plus the fwd and aft torpedo room, fwd and aft engine room would have to be your duty to know better that you know your girlfriends body in order to qualify by the COB and then a qualified officer.
That's what you had to do to qualify submarines (they don't give those dolphins away)
