[Marvel] Why do alien invasions almost always target New York?
gpt
You're an alien invasion, you want to do a hard strike first to knock out the opposition. A majority of superhuman live in New York and surrounding areas, and it contains most of the advanced technology on the planet and the resident Sorcerer Supreme too. Sure, a proper invasion wants to take Atlantis, Wakanda, and Latveria into consideration, but those are mostly isolationist states that you can handle one at a time. If you want to seriously take over the planet, you go after your hard target first.

Now the *real* question is: why don't they drop rocks on it from orbit until Manhattan sinks into the ocean?

Mostly, this is because the folks coming in want to conquer & occupy, not just kill all humans and salvage whatever resources the planet has left.

And the alien invasions that don't target New York are mostly opportunistic. They come through an interdimensional portal or crash land in some area, and they start their conquest from there. Hell, there are aliens that have invaded Earth on accident.
