Mass Effect 3’s original ending brought quite a torrent of hate from fans of the series. There was so much disappointment that Bioware eventually caved in and released the extended cut for the game, which was free. However that may not have been the case. Speaking at a PAX Australia panel, community lead Chris Priestly claimed that they were thinking about charging for the extended cut.
Probably shouldn’t say this; there was discussion [about] should it be charged. And [executive producer Casey Hudson] said ‘No, we can’t do that. We have to make this better. We can do a better job finishing the game, providing clarity, answering some questions.’ And it was very important to the team to end it as best as possible.
Just think of the repercussions if Bioware did decide to charge for it. Fans outrage may have gone past critical mass and who knows what Bioware would have had to do to alleviate it. All we know is that Bioware did release the DLC for free and are continuing to make their games.
