"The whole point" is an easy phrase to misinterpret. "The whole point" of a submarine is indeed to submerge. You are correct - there is a whole lot more than that to be simulated - but Sniper never actually said that was all he wanted, just that it was something important that shouldn't be left out. Perhaps "The main point" might have been better wording, but his intent is easily understood, at least by me.

I agree with both of you. Yes, there is a whole lot more to worry about, but that is something that has been lacking from every subsim except Aces Of The Deep.

As to typing in the actual number, I'm not sure I agree. The captain wants a specific depth, and where using the periscope is concerned he can tell when that's not right, and order a change. But at seventy meters I would think it's kind of hard to know exactly, seeing that it's based on water pressure that changes from time to time. I could be wrong on that, and being that specific wouldn't hurt. I do think it's something long lacking from the rudder, though. The course should be precise, and the compass should make it relatively easy. If I order a course of 310, I don't want 309 or 311. A few hundred miles of that can get you lost pretty quickly.
