I gotta be honest, I never felt that Unova was truly inspired by New York City. I mean, it has it's bits and pieces, but even the region itself does not have any resemblance to NYC. If you compare the rest of the regions to their real-world counterparts, they look extremely identical. Compare Unova to NYC, and they look little to nothing alike. D: The inspirations are pretty nice though, like Liberty Island. The tiny bit of history on NYC was awesome too though -- the one with the reference to World War II.
The Morse code for V on the Statue of Liberty was most likely the inspiration for Victini, the Victory Pokemon, on Liberty Island.
That's a pretty nifty little thing they included.
