I was wondering about u-boats the other day and how it must have been for the Keleuns. No TC, no changable realism, no save or load function.
So how would it be, to have a U-boat and would you even have one. A crew loyal to you, always ready to set sail, fresh fish in the tubes, ready to scare the hell or all the local shiping when you surface next to them. The sea, the weather, everything! I guess it might be kindda fun (you'd really wish for TC after a couple of hours).
I picked type XXI, not because it was the first real sub and it had 6 tubes, or went underwater faster then on hte surface. My reason it has better cabin spaces

and a refrigerator
