Well some controllers have thumb joysticks, which are sensitive enough to do the same work as a normal joystick. I know my Oculus ones can do a myriad of interface options with finger position sensing, buttons, and thumbsticks, but its up to the developers to work with what is available I guess. With the Airlink I could ‘in theory’ from another room to the PC, run MSFS from the headset and fly it without loosing any functionality from if I was sitting with my keyboard, mouse and joystick. This means I could get more flying time as my family does occasionally like me to emerge from my sim room
