Are those supposed to be Phobos and Deimos, the pathetic potato-shaped moons of Mars? Don't bullshit me Bungie. We all know Phobos moves 6 feet closer to Mars per century - and since your 'Destiny' game is set 700 years in the future, that would mean it would have moved only a mere 42 feet closer to the surface of Mars (not even a marginal dent in the 5826 mile orbit there is today). And don't even get me started about Deimos. That moon is supposed to be a speck of dust in the sky, and moving away from Mars at that.
Christ on a bike, if you're going to make a game about space, at least get the orbital bodies of your planets right.

Beautiful skybox > realism. Bungie has already said this.
