Well, for me voice commands are not as important as the simulation of commanding a ship.
Maybe I still want a SW-themed Battlecruiser Millennium with more intuitive controls. So that you could sit in a fighter cockpit and command your wingmen, or sit on the bridge and give orders to officers in their roles, in general take any role on that ship. And with some personnel management like in Silent Hunter.
And with some ship selection, of course. Nebulon-B is different from a CR70, and commanding an ISD-II, eh, I guess without the ability to command that the game won’t be popular among SW fans.
Well, maybe still without taking any role. Like Sea Dogs in space.
