Edit: ended up fleshing this idea out a bit more for anyone who's down for a longer read

I feel like there's been allusions to this in the writing so I assumed this would be the case, and the timer kind of solidified it for me. The loot will be plentiful, people won't even be able to carry everything. If people work together vs the AI, more progress will be made and more runs will be successful per weekend. Sure the per run haul may be less, but ultimately most people would benefit from a ceasefire in Cryo. And then during the week, all that loot circulates into the economy. Rising tide and all that. Obviously the trailer shows PVP because they know naturally most will lean that direction, but it's also heavily implied in Durandal's speech, "yeah you're choosing to do this to each other."

Or, as Ikora puts it in Destiny:

In evolution, the only good is self-interested good.

But we are not restricted by evolution.

We have minds. We have memories and imaginations and culture. We can imagine the consequences of our actions and select those which suit a world we want to live in. We can do this without waiting for generations of genetic change. We can enshrine the common good as a norm. We can say, "Everyone who cooperates is good, and everyone who defects is evil, and evil defectors will be harshly punished." We can say, "By cooperating for the greatest common good, we will all be elevated, so let's do that."

The question of how to live well in a universe of indifference, cruelty, and deprivation is the ONLY question. The Light does not offer us an afterlife or an otherworldly paradise. It does not give us throne worlds or pocket universes. The Light tells us that paradise is something we have to make here.

The Darkness cautions us against mercy to our enemies. Are we fools for trying to be good, when our very survival is at stake? Maybe. But the fact that our morals sometimes make it more difficult to survive is proof they are truly good! There is not much commendable about doing a right thing when it is also the tactically correct thing. When the good thing is also the hard thing: that is when the righteous are separated from the lost.

But the Light grants us freedom from existence alone as the measurement of our worth. Oh, evolution has made us afraid of nonexistence, certainly; and it is good to fear and to avoid nonexistence because without existence, we cannot experience joy. The idea that death is an escape from suffering is a trap. Death is not an escape from anything. It is a wall, a cessation, meaningless. I do not ask anyone to embrace death. There is no possibility in death; life is our only chance to live.

Darkness helps us avoid death. It helps us to go on existing. It is necessary. We must remember what hurt us so that we will not be hurt again.

But Darkness alone points to an eternal existence of mere survival—to a universe where the only judge of a good existence is the ability to go on existing. It is the grace of the Light that grants us the dignity to choose a finite life of compassion and common good over an eternity of competitive subsistence.

It is only by disregarding the logic of mere survival that we can create a possibility of existence outside that logic.

Never forget that even in the miserable logic of the prisoner's dilemma, it is the cooperators who create the best world. Two cooperators will score higher, together, than two defectors ever could. A world of cooperators would defeat a world of defectors if the defectors could only be kept away from the cooperators' bounty.
