Yes, I did know about the Das Boot, extended, extended director's cut, but thank you for pointing it out to me anyway!
I think it was said that there are like, 5 or 6 different edits of that movie. I personally have the 3 hour director's cut, the 563 page (english) novel, and the original sound track. Silent hunter 3 was the crown jewel in my U-boat collection. I have also completed 3 U-boat models recently, a 144 scale U23, a 125 scale U99, and a 144 scale U2540, port-side cutaway to show the interior. Yeah, I really like this kind of stuff, for some reason...
I play this game on the settings that I do because I can be the hero in my own movie, and it kinda sucks if the hero don't win. My careers are not played as 'dead is dead' but 'dead is a bad dream'. However, when I play, if I get killed because of being careless or clumsy, I will reload as many times as it takes until I get it right. Sometimes, getting it right is no more than 'sneak away until we're in the clear'. Maybe I don't get any or much tonnage, but we live to fight another day, and that's good enough for me.
