Hmm agree with you there OP. They don't have to give us the feature of flying between planets. That would be cool if the design behind it was sound but overall it's not necessary. What's important though is space combat and space levels focused on "exploring with your spaceship". These things can only be as good as the designers, therefore, using the arguments that space flight/combat/exploration is unnecessary or flawed is completely redundant. I understand the game doesn't need to necessarily focus on such features as it is a FPS, but if it is to be epic, it should nonetheless experiment and try to offer uniqueness from the standard first person combat once in a while.
