I'm back.
Because I have a real life in the real world, I have never been what many would call a "gamer." But already, I have found myself playing this sim and spending way more time on it than I would have considered healthy, given all I have to do in the real world. I have to admit though, that this sim offers a different type of satisfaction than I've ever gotten with any other shooter. For one thing, I find it very relaxing. I've never played any other sim where I sit down at the computer with a cup of coffee and think to myself, "Well, let's see where we are going today." I really do think that the appeal to this game is the unique combination of strategy and relaxation punctuated by periods of sudden excitement.
So I came back to Pearl after having sunk the ship I was SUPPOSED to photograph. I really wanted to complete the mission as ordered just because to me, that's where the realism lies. So, instead of ending the mission, I opted for a refit and headed back to Yokohama. (no, it aint "yellow fever." lol) I noticed that the refit did not give me a submarine full of torpedoes - only a few.
This time I found at least one ship that called for a Kodak moment. It was a modern tanker. I took the liberty of sending it to the bottom after the photo session.

I got the photo and searched for other ships that also needed to pose for the camera. Couldn't find any other such like ships and so, I headed home. In the process, I racked up a heck of a score in tonnage. When I got back to Pearl, I ended the mission but it showed the assignment as being "incomplete." Still, I received the naval version of the CMOH so I guess the high command wasn't totally disappointed in my performance.
Thanks guys for the guidance. I would never have guessed on my own that I needed to search ship by ship looking for my camera button to light up. That just would not have occurred to me.
BTW, what is the crush depth on these subs? I think that I have erroneously presumed that the red needle on my depth gauge was the "do not go below" indicator. At one point, I found myself with over 1000 ft under my keel and a gang of destroyers closing in on my sorry butt. So, I headed for the thermocline ASAP. The red needle was set at 350 ft. So I guessed the thermocline would be somewhere around 250 ft - or at least I figured I would find it before 250 ft. I never heard any "...passing thermal barrier" warning. When I got to 250 ft, the sub caved in and down I went. Hmmm.
What happened?
Also, does anyone know what effect stormy weather has on the enemy's ability to detect my sub? I mean, can they do better, worse or is it basically the same regardless? It might have been a false comfort, but I found myself in a driving rain the second pass through Yokohama harbor and it felt good. I felt like I had some additional something something to hide behind. But I could be kidding myself.
