C'mon, do you really need Frontier to explicitly tell you that? They built an FPS component that is pretty much disconnected from the flying spaceships part of the game, even to the point where you don't even need to fly spaceships in a spaceship game. I mean, if it looks like a duck and it quacks like a duck.....?
Which brings me to another point. I have seen quite a few posts from some of the settlers on this board arguing that this is NOT an FPS. However the OP is positive towards the game. I've seen likes dished out on this thread from said settlers, but not one argument about this not being an FPS. Hmmmmm.
