Is every character kinda centered around three cities, new york, Gotham, and metropolis?

No. So far, that's just J'onn Jones/Martian Manhunter, Spiderman, Batman (with Spawn/Jason Todd in Bluddhaven which is right next to Gotham), Black Canary potentially (as her writer plans to have her in Gotham), Punisher, and Thor. Potentially also Captain Marvel/Billy Bigs.

Superman and Sep's characters are currently space centered, along with Orion potentially.

John Constantine is centered around England, but his writer is more solo focused at the moment.

Wolverine is currently in the Canadian Rookies.

Arthur is currently in Maine but will be coming down to New York and potentially into Atlantis depending on his story goes.

Our future Wonder Woman is going to be in Gateway, USA, though where exactly that is to be seen.

Sentenial is in Capital City, USA, though where exactly that is is also to be seen.

The Hulk is somewhere in the middle of the US, as are some of the Martians. Then of course, Smallville is there as well.

Captain America and Warbird seem to also be in the US somewhere, but we'll have to see where exactly.

Then we have a person who was considering either playing mutant ninja turtles in New York or to have a hero!Magneto in Genosha, an island nation for Mutants near the African Coast.

So with T'challa, hero!Magneto would be the closest neighbor. And there might be more worldwide stuff happening. New York City just ended up being a good central place at the moment.
