Why wasn't NYC's Central Park concept copied by other cities?

I'm talking about a massive park in the absolute heart of the city. Located such that is naturally surrounded by city high rises. *People are giving examples of parks that are way off in the boonies. I'm trying to say located centrally, heart of the city, you know where the high rises are. Yes I understand nyc has more, the point is centrally located.

Copied by younger cities in North Americ. You know, the cities younger than NYC that could have seen the value of setting aside a large area for parkland before it was developed.
