I've said it before, and I'll say it again: New York, so the teaser trailer and main opening cinematic can open to this:
So, imagine the song beginning and zooming out of the PipBoy of a dead Vault Dweller: "Start spreadin' the news, I'm leavin' today..." A tour around the ruined rooms showing the quintessential Fallout-era posters, before zooming out to show a decayed Statue of Liberty, as "New York, New York..." fades into the howling wind, to be replaced by a foreboding orchestral track, and a chap in power armour.
Fade to black... 'Fallout 4' appears.
Yeah.
