^i haven’t played this yet, but I bet I know. In the X-wing and TIE Fighter games the default setup had the stick control pitch and a kind yaw/roll combo (more yaw than roll) while the rudder input controlled pure roll. It allowed you a full 3 axis flight control that still felt natural but didn’t feel like a conventional airplane. Helped make it feel more like a spaceship in a way.
I bet that’s what they were going for.
Man, I was planning on waiting to get this for a while but the more I hear about it the more I want to just get it now.
