It did not. Why, you ask? Because the story was good and the gameplay was fun. Now I will admit, the ending was sub-par and I'm one of the few people who think the Extended Cut fixed it, but how many other works of fiction were great and ended poorly compared to the rest of the ? Now, I have a few things to say to some people. I'll try to keep it as not-insulting as possible.
First, to all those who wanted a "Shepard rides off into the sunset with his love interest" finale, come on. You KNEW going in they weren't going to have one of those. You had to have seen that coming. Even if you took the "Renegade" ending and Shepard lives, you know full well he ain't going to be walking anywhere. If he woke up and his bones from the pelvis down weren't either powder or made of goddamn Vibranium, he ain't walking into any sunset ever. Look, Mass Effect 3, at its core, is a war trying to be grounded within the realms of Acceptable Breaks From Reality, meaning suspension of disbelief means you can believe omni-tools can do the things they do and that exposure to a certain element in utero can grant, for lack of a better word, superpowers to people. I don't know how many war stories you've read, but endings like that just don't tend to happen in war stories. At least not the ones I've read/watched.
Second, to those who are still saying "the ending needs to be changed to be more like this," you don't know what you want. At all. Fans never know what they want regarding the ending of a game. They THINK they do, but they don't. The ending is kind of lacking, certainly, but come the hell on. It isn't bad enough to declare it the Prequel Trilogy of this decade. I mean, even Return of the Jedi ended with the ewoks beating the Federation. What was I talking about? Oh right, people complaining about the ending. Look, bottom line is that 'yes, the ending is not that good, but it also is not bad enough to declare the whole series ruined forever.' I got the Collectors' Edition, I have one of the discs in my X-Box 360 right now and the other one's on my coffee table, I saw the same endings you did.
