All good points (and others have brought up the surface area bit). Thankfully, by making BB physically larger it actually makes it easier to scale down the civilian casualty percentages - more people are outside the 'You Now A Crater' blast zone, so the rescue efforts afterwards manages to save significantly more shelters. Looking at a death toll of ~100k for BB, ~10k for the counties outside.
This also means the refugee camp outside Providence is host to ~200k people, so I'll need to tweak that a bit to emphasize the madness there. Definitely need to have a bunch more PRT-affiliated capes running security than just MM and Armsy, though... hmm, maybe a good job for New Wave (what's left of them).
Looks more reasonable.
A 100k deathtoll is still bad, but when you compare the 800k death toll from Benjy's visit to Mexico City, there is reason to celebrate.
We're going to see a LOT of displaced people up and down the East Coast.
Most of it in the Greater Boston Metropolitan Area,where Boston will take the brunt, but we will see thousands of displaced people coming into the Philly/Camden area, both from BB itself, and other counties whose economies were devastated by Benjy's tantrum.
This has implications for the social order; among other things, shelters, soup kitchens and the like are going to be stretched.
An influx of BB area refugees is likely to affect Weaver's choice of extracurriculars to sponsor.
It also means that it will be much easier for people like the Slaughterhouse 9 to move undetected in the aftermath, since I expect mass movement of refugees for at least the next year.
While coincidentally making it easier for them to predate travelling groups.
And explains why Dragon had trouble tracking the Undersiders earlier, and it makes it more reasonable that Taylor wouldn't be too worried about how her father evaded coming up on the radar.
Also would provide a neat way to account for New Wave.
350k still boggles my mind a bit, as that's a huge city for only having existed for ~30 years. I don't recall any canonical explanation for this, or did I miss that too? Has anyone pieced together a good backstory for this? Perhaps it became a major port area after New York got hit by Behemoth? Boston is more of a tourist trade port than industrial, so perhaps BB grew so quickly to accommodate the deluge of supplies from overseas during the New York reconstruction era.
I personally don't know of anywhere with that rate of growth.
If we were still operating in BB?
Looking at the extant infrastructure(Trainyard, Docks) and it's geographical neighborhood?
I would suggest that it was a beneficiary of the WW1, WW2 and early Cold War buildup, as part of Boston's outlying infrastructure.
Trainline hookup to Boston, docks to handle civilian and possibly light military sea traffic.
Remember, Boston was a major military shipyard through WW2 until the early 70s, when the navy closed the Chesapeake Yards.
BB could have handled some of the requirements of the civilian shipping industry, to take pressure off Boston's docks and yards.
All that would be necessary is to tweak the number of years since it blew up by a factor of 3, from 30 to 90.
Before that? It was a modest fishing community.
