Why do you think scrapping ideas, changing the scope of a game and even using some of those ideas in later games is new to the industry or somehow of malicious intent? Anyway, here is a video showing numerous core ideas that were changed during Halo's development. A lot of these ideas made it into later games too. One of my favorite examples was the flyable airship [b]confirmed and printed by a major PC magazine[/b] to be playable in multiplayer. This, of course, never happened. But you guys hear some Destiny PR guy mention the word "trade" when discussing how each player makes their own story and has their own unique gear load out and suddenly that means Bungie confirmed player trading but cut it out to sell it as DLC... Enjoy the video.
