Funny you mention that!
I am a huge Wing Commander fan and they also had that “Space Sim” control scheme.
And it makes sense there if you think about it. If the orientation doesn’t matter (because space) the roll axis becomes increasingly meaningless, and you want the maximum accuracy in the pitch and yaw axis. It is just way easier to turn your space ship into the direction you want.
Of course that mainly applies to space ships that have acceleration absorbers (like in Wing Commander) so your body’s orientation with it’s different G tolerances) doesn’t matter.
In Star Citizen for example it matters.
To this day I use my rudder pedals/twist axis to roll when flying most space ships (exception being Star Citizen), it feels completely natural to me.
At the same time I do flight sims with the regular aircraft setup and it feels just as natural.
Marvelous things, those brains.
