Oh, when i say circling, i don't mean it in the sense that you only fly in circles.
What I mean is that, when comparing maneuverability of the various ships, each one has a minimum turn rating, with the lighter ships obviously having smaller "circles" in which to make a full turn at max speed.
(i.e. compare an Anubis and any light fighter in a simple 360 degree turn, and you'll see what I mean).
So when discussing dogfighting, I meant that ships will circle or jockey for the six position. The kicker though is that since space has no drag or gravity, you have no potential or kinetic value for speed, and thus don't bleed off energy in a climb or gain it in a dive. So to attain the best position, you simply have to find the optimum maneuver to get on your enemy's six, and more often than not, a simple right or left turn in OPEN space
will acheive that goal.
That's the offensive maneuver. Defensive maneuvers cover the whole range of maneuvers, from barrel rolls to the Split-S turns, anything in which you evade your pursuer's cone of fire. I think the mouse lends itself well to offensive maneuvering, since you go where you point, but the joystick is much better for defensive flying, since a lot of the maneuvers like barrel rolls are much more intuitive on a stick than a mouse, at least to me.
Besides, a joystick/throttle is so much sexier than a two button/wheel mouse!
