Not played it myself, but it seems very much like "second verse, same as the first". I'm assuming you haven't played the first Destiny if your asking opinions about the sequel, so I'd say download the demo of that and see what you think.
I think I might do what shadow456 said and check out the demo. I would rather have it on pc since that is where I spend most my time. Phoenixgirl what platform do you have it on
