Fallout is a very interesting case. And proves that if the creators of Mas Effect choose to rewrite the ending, that it would'nt be unprecedented. I've never played Fallout 3. But I understand that the ending wasn't to the fans liking there either. And the makers basically said, "Okay. Here's some new ending content for you." And actually sold an add-on that not only included a new ending, but other stuff as well as I recall hearing from a friend of mine who played it. But that's just the broad gist of what I've heard.
But before the ending rewrite, perhaps Fallout would count? Someone who's more a fan of that series would have to let us know.
As to the Potter books - I've read them and thought they were well done. But I think the author needed an editor who was more willing to say "no" to her and tell her to trim things and catch plot holes. In broad terms, I think the ending of that series is satisfying. But I can definitely nitpick details.
But I'm not really a die-hard fan of the Potter books the way some people are. So maybe someone who is could chime in and give their view?
