Yeah, and spoilers of you haven't played it, but Mass Effect 3 does a great job with that on Thessia. In a game where you always saved the day just in time (though maybe a predictable, but still sad, death will happen) it was great. For once Cerberus won. They got there first, took the A.I. thing and almost killed Shepard. All you could do was watch helplessly as Cerberus left with your last chance at stopping the Reapers, them helplessly listen/watch as Thessia is destroyed by the Reapers. That is what Destiny needs.
