I'm a little more cautious about Destiny than perhaps other gamers are.
I do love Bungie. The Halo they created had an amazing universe, with deep, interesting lore, and one amazing sound-track. But, that's all I'd give them; I love Halo but Bungie never were a stand-out when it came to the gaming perspective. If we stripped Halo off it's story and held it up purely on it's gameplay mechanics, I don't see anything amazing. And all the Bungie-developed titles, up to Reach, I feel the same way about. 343 came along and I believe, though sacrificed those things I previously mentioned Bungie did well, produced a much more refined gameplay experience.
So, I expect Destiny to have the things I loved about Halo under Bungie's table, but, I dunno. I'm reserving my judgement and not going crazy till I've played it. Plus, it does just look like the same old thing; that's not necessarily a bad thing, but, I'd have liked to see Bungie stretch their wings a little bit. But, I do very much hope they do a good job.
