I can't live like this - Star Trek: Website

I always use inverted because I’m telling the camera where to go, not where I’m going to look. So if I want to look up, I need the camera below me.
If you’re playing first person you aren’t moving a camera. You’re moving the player’s head.
Which is why inverted y but not inverted x makes sense to me. I move the joystick like I would move my head.
