Well Zelda, while being flawed, was a 1 of a kind. Video games were still new and while Zelda was flawed you're right. It was fun and Destiny is too. But Destiny doesn't have the advantages of Zelda. Destiny is running out of time and mistakes it can afford. Zelda didn't expand so there isn't much worry but Destiny, I worry, will focus to much on flying farther than higher. Just like a glider. It can go far but there's a slow, downward arc and eventually it happens. The ground and gravity take their toll
