And what more could we ask of them, really?Andy Chalk said:BioWare Co-Founder Promises Closure For Mass Effect 3
The ending is out there, and they can't take it back. Nor should they. Nor would it do the least bit to please the complainers. However, they're recognizing what they can do: not change the ending, but clarify it a bit.
The problem with the ending is just how it was delivered. It robbed itself of much of its own weight by failing to deliver a sense of consequence, and by failing to show us "the stakes" while we were moving through it.
I compare it to the ending of the second X-Men movie: Professor X is allegedly in the middle of frying the brains of every human on the planet. This should be causing everything from vehicle crashes to botched surgeries to entire nurseries of newborns in agonizing pain -- I mean, clearly, the stakes are supposed to be extremely high. But we see none of it. We're left to just take the movie's word for it... or we're expected to relate to the more immediate peril of the heroes themselves, which just doesn't work in that movie.
The best move from here is to create content that shows the impact of Shepard's actions and choices. There could also been some "meanwhile" DLC, which allows players to act out what various other characters were doing while Shepard was bringing an end to the conflict, and that might add some gravity to the events surrounding the ending.
I think some free cinematic content would go over quite well, in addition to paid playable content.
