Inspired by @fuckingshit's post, I'd like to know your opinions on games with really bad or disappointing endings. Sometimes games do great for almost all of it, only to totally ruin it at the end.
I'll agree with Mass Effect 3.

I don't think it needs a happy or sad ending, but what we got was utterly disconnected from the previous choices. When they had the sidequest for Tali and you entered the Geth cyberspace, I thought it would be connected to the ending of dealing with the Reapers. It would've been satisfying and thematic to nonstandard ways of solving problems. It also lets the Quarians have a victory that shows that engineering and creating wasn't wrong. Hell, the Geth could've worked with them and patched their history. It would reward players who maintained good relationships with their crew and make the victory a shared one, fitting with the ideal of the Citadel.
Instead, it was a one-off quest that said nothing of the the game as a whole and there were no other big choices that affected the ending.
Anyway, what games had awful endings, and if you want, how would you have changed it?
In the spirit of preventing unwanted spoilers, could we tag them in this post?
There's this weird quirk in the final Mass Effect cutscenes which remains unexplained except by the indoctrination theory, where Shepherd's eyes have the sharingan thing in them that signals that a person is indoctrinated on both the synthesis and control endings, but not in the destruction ending. That's lame in its own way though, since it implies that the ending choice is actually just a multiple-choice test that you can pick the wrong answer on, but it's something.
