Ah there have been allot of things from books movies tv shows ect..one could make the point that in a way Starship Troopers the book by Robert A. Heinlein is quite like Halo. We could use Frank Herbert Dune as well. As allot of media could be Referenced in many ways with like minded themes . Destiny Differs as the story is not one of a great legacy of hero's such as the Spartans, ODST's, Marines all apart of the UNSC against the Covenant. Halo showed a narrow slice of that universe. While the Master Chief is a hero in every part of the word. The story focused mostly on his actions that shifted the War into the Humans favor from his perspective. ODST and Reach were exceptions. Destiny will have many heroes that you will play as becoming a legend in your own right and actions the Community does will help events in a ever changing world that you go out and try to reclaim the past of once was. Building the hero from the ground up as you define what you are as a Guardian. It might seem akin yet Destiny thus is not. Its a Fantasy/Sci-Fi set in a whole different universe where one city is humanity's last refuge instead of the UNSC who had colonies that were burned until only earth was left. Fiction differs as well as the view outline and even what the game play to the content of it will be. Fps is Halo Like. With the innovative extras Yet no open world. While Destiny takes a fresh approach. Being a Kind of Fps mixed with MMO and Rpg like. Open world with Char building social diverse structure and Adventure Galore as you quest with friends into dungeons or other worlds to find treasure. Kinda like a table top Rpg come to life. So no they are not alike as Halo is more Sci-Fi then fantasy. Destiny has a mixture of the two but is far greater than Halo is due to the concept fiction and idea of open scope world play. This sets it apart. While there are things like Forge in Halo so much can be made to put into Destiny that it would leave Halo behind. Its like comparing a Ford Mustang(Halo) to a Lamborghini,or Mercedes Benz(Destiny).
