I know what You mean, but Bungie never demented that they got their Inspiration from other games/ movies. You should although consider, that many movies and games from the last years have contents and plots, that we've already seen before. Even Halo was partially inspired by a novel from the 1970's, called 'ringworld'. And was it a bad game because of that!? Definiatly not! I don't want You to like Destiny, but You should give them a chance. Bungie is working since five years to give us an entertainig adventure. And in my opinion they have done a fantastic job so far.
