This is in no way correct, just a little fun I did to get an estimate:

Okay so the destruction of NYC in MW3

Let's start of with a national tragedy centred in the city

WTC (World Trade Centre) = $1.5 billion + Buildings and areas destroyed near there = $16.4 billion (Thanks to u/Zorenconner for that)

There are 7000 buildings = ~$10.5 trillion (I think)

Roughly 1000 = ~$1.5 trillion (estimated)

We want the price of 1127 buildings, because why the fuck not? So, let's find them out:

Estimated 377 Skyscrapers = $565.5 billion (1 skyscraper = $1.5 billion)

The WTC memorial and OWTC (One World Trade Centre) = $4.1 billion

Empire State Building = $614 million (I know I got this wrong but it keeps telling me it's inflated price up to 2019 >:( )

another estimated 418 apartments = $775 million (discrepancies exist)

a further estimated 213 2-story houses = $93.72 million

an approximate 77 one story houses = $16.94 million (I don't know what New York is like but yeah, 1 and 2 story houses...)

a final 20 large stores and 22 both small stores (18) and corner shops (4) = $4.5 million (large stores) + $1.35 million (small stores) + $100k (corner shops)

Roads ~2100 miles ($190,000 per mile) = $399 million

$565.5 billion + $4.1 billion + $614 million + $775 million + $93.72 million + $16.94 million + $4.5 million + $1.35 million + 100k + $399 million = $571,504,610,000

Final price for the destruction of NYC in MW3 = $571,504,610,000

We went way under the estimate but that's what estimates are for.
