Whatever floats your boat (sorry, couldn't resist
).
But yes to each his own. I do agree that linking rudder to any sort of axes would be very odd, and take away from the sense that, as previously mentioned, a caption gave orders and did not "drive" the sub.
This is one subtlety that actually appealed to me about the sim. It really helps to create the sense of
commanding a large vessel. Compared to the impulse control of a speedboat, this is a rare feature to games and sims in general, and makes control far more practical when not looking directly ahead on the conning tower.
I'm new myself but welcome to the forums!
