Have faith. This is Bungie we're talking about. Yes, they were rushed by Activision, and yes, the story is... limited, but they are listening, and they are going to make this game even better. Look at the immense support they gave for Reach until the bitter end, and that was a game they knew they'd be kicked off of within a year or two. This is something they want to persist, to continue in iterations for a decade. People won't buy 2 without a solid 1, and tehy have a big interest in making this as good as they can. They'll expand it, just be patient. Play something else and come back once in a while until the expansion. It'll only get even better from here.
