I genuinely don't understand the point you're trying to make. 500 million was the base fund for the franchise, Destiny has accrued billions in profit off of the very first game in its' 10 year saga. The 500 million is guaranteed to go towards game production, but they can throw as much of their sales money at production as they want as well.. My point is that Destiny 2 and beyond will have drastically higher budgets to work with. Halo 5 was the most expensive game ever developed at just over 200 million in production costs, think about what can be done with the funds Bungie now holds for sequels to Destiny. Destiny 1 was a budgeted and heavily rushed game with all kinds of developer infighting and design direction conflict, Bungie didn't know how successful it would be so they spent very little on it -now that they know that there is a demand for a game like Destiny, expect no such reservations in the coming sequels.
