As much fun as I've had with CE, I still much prefer the large scale design of VoG. Although it's technically linear in encounter progression, it still encourages exploration with branching paths, hidden alcoves and offers a level of wonder as you take it all in. It feels believable.
Crota's floating castle in the underworld of the moon looks great aesthetically, but feels out of place environmentally. Being the "hive" and burrowed underground in the moon, I was expecting endless mazes and tunnels full of thrall leading to vast caverns filled with hive centric architecture. The fact that you actually load from the pit area to the bridge area crushes my soul a bit, much like the small circuit based designs of the planetary patrol levels.
Looking forward, I'm incredibly disheartened by the new raid's name being "The Arena". It implies a fairly static area where multiple encounters take place. I've never been a fan of this design model when it comes to raids as it feels cheap and obviously lacks in the areas I enjoy the most: exploration, discovery, environmental variety, etc.
That's a lot of inference and speculation on my part and I certainly hope that's not the case. The fallen is my favorite enemy race in game and I'm really hoping for a deeper expedition into their world in HoW. Unfortunately, Destiny has fallen short for me in a lot of these categories while excelling in others
If Destiny embraced, lore, narrative, open world, exposition all in game as much as it did the tactile experience that is playing the game, it could easily be in my GOAT considerations.
