I suggest you read this (Destiny)

So we're on the same page--what are you expecting from a sequel?

To me, TTK felt like an enormous step forward. It felt more like a sequel than an expansion pack.

This is mostly due to the amount of new content (I've played two nights on only one character and haven't come close to completing the content), the new story missions/cutscenese/storylines blowing the old story out of the water.

I completely disagree with your critique of re-use of assets. Dreadnought is enormous and new. Going back through old spaces was used lightly enough and in novel ways to still feel fresh. I particularly liked going through the Crota raidspace solo.

I know a lot of people didn't like D1, and I have probably sounded like a Bungie apologist in the past--but wow. To me, these new cutscenes and story missions were jaw dropping. In my own dense way, playing through TTK made a light bulb go off in my head--I finally understood the disconnect between what people wanted out of Destiny and what it actually was. TTK made me excited about the present of Destiny and gave me "hope for the future."
