So I recently grabbed a copy of Destiny because friends were playing it, and... it's very pretty, but kind of empty. I'm still a level 6 baby right now, so maybe shit opens up and story becomes more prevalent, but right now I got an intro tutorial, and then a couple "story missions" which consisted of "hang out in this area while my timer runs down, and shoot stuff."
Story, so far, has been thin as hell -- which contrasts even more when compared to how lush the world looks.
In an earlier thread someone stated that the website/app was where the actual story is told, the background for everything, so I downloaded that, but there are just some cards with fairly generic description text. Others have pointed out that Activision interfered with Bungie's plan for story, and it has been bowdlerized. Don't know how they'll restore the story to it, but it would be nice to have a little more idea what's going on four hours into play.
The gunplay is pretty good; I feel differences in the weapon types, though even in the starter area I've found a couple enemies which ping "IMMUNE" to my puny attempts to plink them to death.
