Well, to get the best out of the practice, I believe Condor has a recommended equipment list for controls. A decent joystick and rudder peddles is recommended.
Yes, you can use the "twist" function on a lot of joysticks for rudder, but you lose a bit.
I will say (as a gamer as well as ex CFIG), you still lose a lot of "butt feel" on any PC based simulator. I have flown Condor, not a bad way to go, good controls to the PC make it better, but actually flying is best. But I will NOT discount using Condor as a tool.
Same goes for RC Soaring, you lose a lot of butt input, but the basics are the same.
