Executive producer Casey Hudson has warned that even with the changes implemented in Mass Effect 3's Extended Cut DLC, not everyone will be satisfied.
"There was some feedback that we can't address," Hudson said in a BioWare podcast, as reported by OXM UK.
"There are people who just outright rejected the whole concept of the endings, and wanted us to start from scratch and redo everything. And we can't do that because that's not our story, we wouldn't know how to write that story."
Although some critics have judged BioWare harshly for bowing to fan pressure over the endings, Hudson said BioWare aims to 'delight' players with its stories and give them "amazing worlds to escape to", so it just didn't "make sense to make some kind of artistic statement, and then turn our backs on it forever".
That said, he's well aware that a whole new can of worms has been opened, since it's impossible to "completely satisfy everyone".
"We've seen a whole range of feedback, ranging from people who wanted a total redo, to people who had concerns and questions about the original endings, to people who loved the original endings and have told us they don't want to change anything," the developer noted.
"So there's no doubt that there will be a whole new wave of discussion and debate, maybe even controversy. But we didn't do the Extended Cut because we're trying to make everybody happy, make it perfect - we just saw an opportunity to expand on things that we felt could add value to the experience, for those that appreciate it."
