The DLC probably won't please everybody, but I feel like the Extended Cut is the way the game should have ended in the first place. It all comes without fundamentally altering the multiple ways that fate can shake out.
Luckily for both Shepard and those fans, the new content in the Extended Cut provides plenty of new details about the ultimate fate of the galaxy. But it could also represent the thoughts of many fans who felt Mass Effect 3's original ending options were too bare bones and not nearly meaningful enough for the conclusion to an epic, three-game story that could easily span over 100 hours.
This line is one of the new, player-selectable dialogue options available during a climactic conversation in Mass Effect 3's Extended Cut DLC content.
