With the huge lack of story content in this game, It really appears that at some point in the development, Bungie just gave up on the idea of a single player experience and just pushed out a co-op, multiplayer grind fest. When you look at all the developer diaries before launch, it really seemed that Destiny was going to have this epic scale story campaign and that the multiplayer aspect would just be a bonus. This really reminds me of Aliens Colonial Marines. Amazing dev diaries, really exciting trailers and then when the game launched, it was like "um what is this horrible mess you dumped on us? Where is the game you have been showing us the past year in your development diaries?"
