Ok, I am a total noob to Starfinder and my group is trying to understand starship combat rules. In our first combat we couldn't find a reason why a pilot would choose to move through a ship if flyby allows to make your movement, and if you fail the roll the only penalty is to take a free attack from the ship...exactly the same as in Moving Through Other Ships.
Can anyone point me out what we are not understanding?
If you make a successful flyby attack, then in the gunnery phase you can fire from any arc of your ship, onto any arc of your target at a range of 1 hex. You can use your preferred weapons, regardless of where the ship's end up at the end of the helm phase.
So, if you lose initiative, and need to move first, making a flyby attack successfully will mean that no maneuver your enemy takes will allow them to get out of your firing arc.
