"Pak: I think there was probably more going on in World War Hulk. World War Hulk tied into a few more ongoing series. With Chaos War, just because of the nature of the story, we have this great opportunity to play with characters that we haven’t seen for a while, namely Alpha Flight, and the characters in Fred’s Dead Avengers book. It made sense to do tie-ins that were especially created for the event, as opposed to tying into ongoing books with those particular characters."

Isn't that nice?
