I agree on using the camera view, both external and event. Without them you miss the beautiful graphics and lots of action. Whats the point?
As i have mentioned before when it comes to torpedo targeting this was usually done by the weapon officer, needless to say that was his most important job. So if you (the captain) do the calculations yourself you are not playing with realism
But who cares about realism, its not very accurate in SH3 anyway. The main thing with any game is to have fun :|\
