Gaming is a business, first and foremost. They need to make money, lots and lots of money. Why? They have a half a billion dollar budget to justify. That means they need to pull every trick in the book out and put it to use. I don't think you really grasp just how much 500 million dollars is. If you were to count that much money a dollar at a time, and you could count one dollar every second, it would take you nearly [b]16 years[/b], and that's with not even 1 second lost on breaks to eat, drink, sleep, or use the toilet. It's a ridiculously large number. They need to justify that ridiculously large investment with ridiculously large profits. By chopping down the total content that is Destiny, and then scattering it across a ten year span, gives them a huge opportunity to make a return. Not until Destiny 2 comes out will Destiny be "complete". It's literally in Activision's interest that Destiny remain incomplete until that time so they can sell you more content. Studio makes content. Publisher releases content. Consumer buys content. Simple.
