I definitely think it should be a full sized expansion. "The Golden age". My main concern was that too much variety in the weapons would diminish the Sci-fi feel, as there would be just as many golden age weapons as currently, lol. Really hope Bungie implements the idea, and doesn't botch it like No Land Beyond

Certainly! Though, one question still bothers me... Did they truly intend for the game to be a "Shared-world shooter?"

Certainly the Golden age is a large point of reference in the story. Though it's hard to say if they intended, or intend for it to be a topic further pursued. Not much more than Rasputin and a couple guns have really been touched on
