Yeah it's not an FPS, trying to line up your gun sights with a mouse isn't anything like doing so in a typical FPS game. I mean we could have made it so your guns track where your mouse is and shoots towards that but then we would have a balance problem on our hands so we didn't. Plus this game incentiveses pitching and rolling not yaw so even if they do use a mouse to aim their ships it's going to slow going for them if they expect it to work like a FPS. Much better to roll and then pitch to turn for example.
Now what mouse control system is ED going to use? I know of two schemes that are done in games, those are
a) Mouse position = joystick position. A cursor may either be displayed and used as a freely movable crosshair (e.g Freelancer) or the cursor is hidden and weapons and crosshair are still fixed in a forward position (e.g. Strike Suit Zero).
b) Mouse position = spaceship orientation. Rate of change in the mouse' position equals the rate of change in the ship's orientiation (which will also lag behind that movement, of course, due to simulated inertia).
Scheme b) has the disadvantage that it is virtually impossible to maintain a steady rate of rotation ever, it will always be jerky, because it actually is basically identical to how an FPS is controlled. It also requires to lift up the mouse and reposition it frequently in tight maneuvers, or set mouse sensitivity extremely high and thus trade in precision for the reduced to move the mouse around all the time.
Scheme a) has the disadvantage that is is virtually impossible to maintain a straight heading unless mouse control can be actively disengaged. In the case of Freelancer, you could use spacebar to toggle between mouse control on and off, additionally mouse control is active whenever the left mouse button is being kept held pressed (in Freelancer, when mouse control is off the mouse can also be used to interact with the HUD).
I am now wondering which of the schemes ED will employ. You agree with a post that states ED will be nothing like Freelancer in terms of mouse control. But Freelancer indeed uses the much smoother scheme a), thus I am now worried we might end up with scheme b), which I consider absolutely horrible, to the point where I think games like that are unplayable with a mouse.
Or will ED use a different solution c) which I am simply unaware of?
