My version of the Captain's cabin is a bit more mundane. Sometimes I go periscope depth, TC 1 and put a wireless headphone on. Then I can walk about the house and do all these disgusting things one needs to do like wash the dishes and laundry -but still be aware, if the sound man reports a contact.
If only the wife would accept me talking to her with headphones on. But she finds it annoying if I suddenly dash off to the computer in the middle of a conversation. I even tried introducing her to the game, but she is a different kind of a nerd than me.
I'm waiting for the day when they can connect SH3 to sunglasses, like a heads-up-display kind of thing. Then I could sometimes try what a patrol made mostly at TC 1 would feel like. I would be on the beach or shopping and at work, yelling sound commands to my microphone: "Alarm! Crash dive" and "Open Torpedo tube 1" etc.
