I'll give them one thing (actually I'll probably give them a lot of things, including my money when Destiny comes out) Bungie knows how to do a really good 'sky'. Destiny, however, pushes things to the maximum. Not since Red Dead Redemption have I been so compelled to just sit on my arse and watch clouds move. This time-lapse video exemplifies everything sexy and glorious about Destiny.
In fact, since the moment I turned the game on, I've been waiting for a video like this. I wonder what took so long.
It reminds me of just how important skies or skyboxes are in video games -- especially if you're trying to elicit a sense of scale or wonder. Bungie has always been a master of this. I'll never forgot stepping onto land in Halo for the first time, noticing that the 'Halo' world actually stretch over my head and into the sky. Just that detail, that sense of place -- it meant everything. It gave the world a sense of legitimacy.
Destiny doesn't necessarily need anything to make its story or high concept ring true. It just wants to look purty. Mission accomplished.
