Game mechanics are game mechanics. You have a controller with some buttons. The best you can do in this category is create something that is fluid and not frustrating. Take the best of what's out there and refine it. Now the story, the adventure that you're going to experience is unreal. That's original. That's why we play games, to get lost in an epic saga. To become legend. Bungie and all the hard working people there are pouring their lives and passion into this game. They are tirelessly creating something you've never experienced before. In its scope and scale. They way you interact with it and how it's being presented. Truly next-gen and then some. At the end of the day people are going to love it or hate but to formulate a spiteful attitude before experiencing Destiny hands on is poor gesture to the people who created it.
