If you plan to buy joystick or HOTAS JUST FOR SC, I suggest to put on hold first an see how the DF module turn out. I have the feeling SC will be less of a simulation/immersion and more to mouse arcade type of game to appeal to the mass. For examnple, in War Thunder us stick users are at severe disadvantageous in Arcade Battle mode due to over precision of mouse. Only in Full Real Battle mode, mouse aim is disabled and can only be played by stick users. If SC disable mouse aim, but using mouse cursor to emulate joystick movement on screen I think only stick users will have fairer chance against mouse users. For space sim a HOTAS without rudder pedal is enough. Rolling can be applied to the twist stick function. In normal atmospheric flight, it's hard to take off with rudder control on the twist stick and the twist stick axis can bleed into the pitch axis so that's why a separate controller like rudder pedal is required. Mapping to keyboard will only kill the immersion experience in a flight sim. While executing maneuvers, the slightest input on unintended axis will send your plane to flat spin and come crashing down - enlarging the deadzones will only decrease the accuracy and precision. For that extra 2 movements in 6DOF that isn't available in atmospheric flight, heave (vertical up down) and sway (horizontal left right), I think it will be easier if mapped to a hat switch on the throttle if you have a HOTAS or a hat switch on the joystick if you don't have throttle. So if you play flight sim and space sim like SC - go get HOTAS and rudder pedal. Only space sim - probably joystick, probably HOTAS. In space sim by default - pitch and yaw is mapped to the stick by default. Atmospheric flight - pitch and roll to the stick. Yaw to rudder pedal or twist stick.
