Mass Effect 3

Mass Effect 3 is the final game in the Mass Effect trilogy, whose ending was so controversial that people filed complaints with the FTC about it. It was also a Wii U launch title for some reason.

Glitched Zaeed Dialogue

By importing a Mass Effect 2 save file in which Zaeed survived the suicide mission, he'll appear in a short sidequest in Mass Effect 3. Afterward, Shepard can speak to him in the refugee docks, but most of his conversation loop does not actually trigger despite the recorded dialogue being present in the game files.

One of the game's writers stated at San Diego Comic-Con 2012 that the conversation loop broke several days before the game's release and the programmers were unable to fix it in time.
