Well, they do make small changes to the universe with the "Crisis" events, but after the crisis the changes are made known and fit in with the story due to the nature of the crisis events.
Marvel retcons the hell out of their universe and gives no reason for doing so. The editors expect the fans to just forget all of that "stuff" from the past. pisses me off. Goodgod im a nerd.
