I'm personally in it for that whole 'feel'.
And I think it's too simplistic to say something along the lines of '

' or '

' about U-boat crews. You have to realize that they were people called up to fight in a total war. There was a lot of good and bad guys on all sides of the war, but in a battle 'good' and 'bad' is simply a matter which side you happen to be on. A U-boat sinking
your ship is as bad as a ship sinking
your U-boat.
I'd never be particularly interested in war were there not a sharply controversial humanistic aspect to it. I hope this isn't taken the wrong way, but I'm fascinated by people pushed to the limit - and not in the sport-like sense of it, either - but totally in a life-and-death sort of way. And the Battle of the Atlantic certainly did that. It's one thing to judge war sitting at a desk at home, and another thing to judge it with your finger on the trigger of a weapon aimed at an enemy.
I'd never confuse a game with reality, of course, but things like that are always in the back of my mind when I play wargames. Likewise, some imagery in SHIII is amazing food-for-thought for thinking about the conditions as they really were.
