You haven't proved anything at all. The reason I asked to provide even one example is to point out you are 100% wrong. A dev won't even attempt it because it makes zero sense and wouldn't work. TrackIR seems great in theory but id rather not be moving my head around to get the screen to move. Have you ever played the WC series or x wing vs tie fighter?
Yes, I've also played the Elite, I-War, Freespace, X series and plenty of others. Heck, even Battlecruiser Millennium. I also have a several hundred dollar HOTAS and rudder pedal setup and have played numerous flight sims of all level of complexity, including the likes of Falcon 4.0 (my favourite) and Jane's F/A-18. And like I said originally, this is a space combat sim, it's no Falcon 4.
So why wouldn't it work? I've already told you exactly how it can work and your only answer is "but no games have done that". Developers haven't done it because it would be complex and unappealing for the general video game audience these days, which is pretty much exactly the same reason we don't get any space sims at all anymore. But this game isn't aiming for that audience.
Maybe you aren't able to perform key combinations that require pressing more than a single button a time, but that isn't the case for me and dare I say plenty of others who can handle complex controls. Like those who enjoy I-War 2 with a 360 pad for instance.
But it's moot since farther down you admit defeat by saying you would use a keyboard supplement. That wouldn't really work either unless you had some special one hand controller.
I kind of feel like you're being deliberately obtuse now.
First of all I didn't say that it's what _I_ would do, I was saying you could do it if you didn't want to cram so much onto a controller. If I was going to use a controller myself I think I'd have no problem with mapping it all on there.
Secondly, I think it was clear I was talking about the rarely used commands that don't need to be directly under your fingertips. I have no idea why you think that would be a problem. Why on earth would you need a one handed controller to take one hand off the gamepad and tap a key for some function that's infrequently used? Do you actually use fixed external cams in the middle of a dog fight so that you need them immediately beneath your fingers? Or the button to toggle on/off the grid on the navigation map?
I've done the same thing in flight sims for keyboard shortcuts that I've not had mapped to my HOTAS (real world fighter pilots take their hands off the stick or throttle to press buttons too).
The point is that some stuff is fine to delegate to the keyboard because it doesn't need to be so immediately accessible. Commands that tend to be used during "downtime". You could also bind them to the controller using modifiers, but it isn't necessary to do so in my opinion.
This really isn't as hard as you seem to think it is.
Edit: In regards to TrackIR, the head movement isn't 1:1. You adjust the sensitivity so it only takes small movements to use, much like using a mouse with your hand. Just mentioning that in case you didn't know (people often don't realise that about it).
