I think the difference in money between them is exactly it, but in how many developers it took to make and how many it still takes to continue to add to it. There is no chance that Warframe had the capex or opex of Destiny at any point in either game’s life.

And as much as people’s minds can be blown by the size of executive bonuses, I have yet to see reporting that ties it as a major contributing factor to why games became too expensive to make or maintain. That cost is mostly in just how many people those games employ to make them multiplied across how many years they’re working on it.
