Which part of it did you want implemented? The part where you needed a flight joystick to play it to the best of it's abilities? Really, any real flight sim will of course beat a rail shooter, but you can't ask Bioware to add something in game that requires more than what the average gamer has to play it correctly. Especially because MMO's thrive on mass appeal, not niche appeal.
Rail shooters have mass appeal because they have easy controls and all you need is your keyboard and mouse. Flightsims have niche appeal because you actually need to spend money on hardware to experience it to the fullest. And all 'flightsims' that do it differently all fall short in fun factor compared to simple rail shooters (mouse flying is an abomination, that is my honest opinion).
I just wanted to comment on this part... I played SWG from beggining to end and the only part of the game i ever enjoyed and spent countless hours on was JTL. But having to buy a flight stick is not true... many of the best pilots across the servers used the keyboard and mouse.. The mouse actually gave a edge during pvp because of the twichy reactions made it harder to track. Yes i went out and bought a saitek stick and throttle... but only because it made me feel more like a pilot.. nothing more. dont take this as an attack.. im just pointing out a fact from a game im familiar with.. star fox on the other hand.. never played it.
