Hi ! how is it dealt with the lots of command keys and buttons we usually have in flightsimming?
You have to use a sim that have clickable cockpits to be able to fly anything more complex: I can easily fly any plane in P3D using only a T16000M and clicking on the cockpit. But to fly DCS (e.g. Mirage 2000) I have to use a X65F throttle and my T16000M, else the "combat" controls - radars, etc., aren't doable using the clickable buttons.
I'm quite certain any WWI sim can be used with a single joystick (as I flew both WOFF and ROF), and any WW2 would need only a
HOTAS setup (to encompass the more complex engine management - else you can still use a single joystick) to work with no issues.
