I'm really starting to come around to Destiny. While this is more or less the walkthrough we saw back at E3, seeing it in HD as opposed to on a live stream while mentally and physically exhausted has done wonders for my anticipation of the game.
That opening shot in particular is just spectacular. For me, the big draw beyond the obvious Bungie-made first-person-shooter gameplay will be the distinct worlds of Destiny. Skip to the end if you want a reminder of what's in store on that front.
