A comic book is excellent because there's no gameplay, and it can portray the story better.

Besides, now we can pick up and throw skyscraqers in a destroyed 2013 NYC.
But in a comic, you can't live the story and might even get too lazy to finish it due to the fact you know they'll see each other New York City again. Don't forget in the E3 3D Trailer we saw Prophet, meaning neither the sphere was destroyed or the aliens attacked further.
