Can someone tell me why just about all of the action in the Marvel Universe takes place almost exclusively in New York? I've primarily been a DC guy most of my life. However with the new Marvel Now, I've been giving that universe a try. The one thing that I have found a bit jarring is that the world feels small compared to DC. In the DCU just about every member of the Justice League or the Titans spends their time in different cities. In Marvel, regardless of the team, they all seem to hang out in and around NYC. Is there a reason for this?
