I sort of think the same thing, though apparently the other players "changes" to the world don't show up until you complete the first delivery into that area. So everyone is going to have a hard time of it at first, but if everyone works together then the idea that people will be putting down freeways to make the experience much easier seems to have some truth.
I think it's interesting, but I'm curious if it actually comes to fruition that unlocking the mystery of the "Death Stranding" and reconnecting society will depend on the social element.
It would be cool if Kojima is testing the idea of "social" networking by having different servers give different visuals during the endgame or something.
Like, if you were on a server with a bunch of solid folks, when you arrive on the West Coast to complete the game, there is less bleak imagery of 'Death Stranding' stuff and some lush greenery regenerating around a bustling city or something, instead.
Or, if you played offline totally, or on a server where everyone devolved into isolationism and hoarding supplies for themselves rather than leaving them in lockers and safehouses, the environment remains bleak throughout.
The missions and the story remain the same, and even most of the cut-scenes, but the visual atmosphere is altered as the character reaches the end of his journey, and maybe you get an 'A, B or C' ending situation depending on user interactions and total number of 'likes' that humans shared with other humans.
I doubt it goes that deep, and it's likely just Kojima making some type of witty commentary on social media and society... but it would be dope if the game itself changed based on his measures, rather than him just pulling one over on everybody with a massive, pointless fetch-quest game.
