10 Video Games Whose Best Ending Was In DLC

10. Broken Steel - Fallout 3

The ending of Fallout 3, where the Lone Wanderer must sacrifice themselves to return clean drinking water to the wasteland, would've been much more effective, had the game not provided you with a Super Mutant companion who could easily do it for you and not die from the radiation. In the base game, Fawkes' fatalistic philosophy is what keeps him from going into that room for you, but due to fan outcry, Bethesda created a DLC to address this. 

Granted, the Fawkes dilemma wasn't the only reason that fans hated the original ending. The true reason was that it, well, ended the game. So whatever sidequests you had left, or areas left unexplored? Well tough break, buddy. Bethesda made Broken Steel to tie up both of these controversies at once, filling a plot hole, while also (and more importantly) letting players continue exploring the world.

In Broken Steel, you survive the process and wake up 2 weeks later in the care of the Brotherhood of Steel, who are renewing their fight to cleanse the Capital Wasteland of Super Mutants and the Enclave. You decide to help them because really, what's the alternative? Fight against the guys with the giant nuke-throwing robot? 

Broken Steel not only addressed fan complaints about the ending to Fallout 3, but it also gave fans an entire expansion built off of that. And the new ending is significantly more satisfying as a result.
