Though I'm still playing through and yet to finish it, one email log you can get in Death Stranding explicitly raises the point "we have no idea what's happened in other countries". Global apocalypse stories have a lot of potential for repeating the same overall disaster in a sequel but to another distinct population with distinct conditions, leading to different stories. I'm struggling to think of where that approach has actually been used though. (Did the Walking Dead do it for their side show? Not sure, didn't watch it, just heard about it...)
RE7 and Revelations 2's most horrifying concept that personalities can be spread via infection and effectively become their own entity each time is probably one of the better sci-fi concepts they've introduced, and I especially love that they are not a hive mind and will actually fight each other.
hiveminds went from an earnest attempt at portraying a cool scifi concept into a way to save on developing ai behavior
