I had an old Cyborg 3D joystick laying around and tried it but the surprising thing was I actually preferred the mouse and keyboard.
I know its a shocker.
I guess the last Space Sim I played with a joystick was Privateer 2, which was nice.
But after that it was Freelancer with a mouse, which I loved.
I also played the X games with a mouse, which was serviceable, as I wasn't really into dogfighting in X anyway. More exploring, trading, building etc.
I got the Logitech extreme Pro 2nd had (but in good condition) so it was a very small investment. So no big deal if I prefer the mouse+keyboard option.
As I haven't actually bought ED yet and am waiting until it goes live, I have plenty of opportunities to wait and see how the Mouse+keyboard option develops over the ED project lifecycle.
It's very promising you saying it's a good option though.
I should add the dogfighting/PvP aspect is going to be secondary for me anyway.
I'm looking forward to trading, exploring, upgrading the ship etc.
So it may well be that the Mouse+keyboard is "good enough" for me.
