Please. GSF is on a rail, the rail is just disguised as a bubble now. You have the "freedom" to attack the points in the center of the bubble and the other people attempting to attack the points in the circle. That's it.
And it's still the craptastic "hanging christmas ornament puppet" spaceship you're "flying".
Just so I understand you right... you see a 3D-environment in which I can steer a starship in the direction that I want without limitations, as long as I stay within the 3D-area at all... as "on rails" ?
So anything beyond an infinite universe is a rail shooter now??
