I think them changing the ending is just not gonna happen. What I believe is not so far fetched and so important, I think thats what you are hinting at, is they should flesh out Priority: Earth. The last mission just sucks and is clearly super rushed and dearly needs more content.
When I say fix the endings, it's the entirety of Priority: Earth.
i mean, no one would do that. mocap and implementation is prob the most expensive part of gamedev.
Would it cost more than Shadow of the Colossus lastest remaster, for example? Also, there would be a return. EA will not simply give away the remaster for free. A reworked final streth for ME3 would make the game way more appealing.
They bother because tons of people still want a remaster. Even as someone who was initially let down by the ending myself, I've since gotten over it and I think a majority of players probably have as well. They're not going to siphon off the resources needed to change missions, change the script (that itself requires them to go back and make sure it doesn't break the rest of the script), record new VO, make all new cinematics and so on for an 8 year old game. I don't know any publisher that would.
Heck, that's not even taking into account if people would even like the hypothetical new ending or create an all-new controversy and headache for Bioware lol. Come on now.
It's not even the ending that bothers me (Priority: Earth does) it's its legacy. It's a taint on the Mass Effect trilogy that I wish to be gone. I don't want that * everytime some one brings it up.
And as I mentioned, of course it would be a costly affair, although I don't think any more than a DLC like Citadel, but I believe it would be worth it, both financially and thinking about the future of the franchise. A remaster shouldn't be seen a quick cash grab with minimal effort. That so many publishers think of them this way is why so many are terrible.
