I don't know, the ending kind of invalidated all of the previous decisions for me though, I mean, what's the point if no matter what your going to end up having the same 3 crappy choices, which really aren't that different from each other? It doesn't matter who survives Virmire, it doesn't matter if you killed Wrex or not, it doesn't matter if you saved the Council or not, it doesn't matter who survived the suicide mission, it doesn't matter if you destroyed the collector base, it doesn't matter who you romanced, nothing matters, because your going to get pigeonholed into the same crappy decision.
I hope they come out with a DLC to fix it, something along the lines of it being an indoctrinated hallucination, which is why the kid was there(who during the whole game I had sympathy for, and got that he was representing all the lost souls on Earth, and throughout the rest of the galaxy, but after that ending I just ended up feeling contempt for the little **** for being the messenger that brought on that horrible ending.) and that the Catalyst does something else, and we can beat the Reapers, and not have to bring back the galaxy to just a few years ahead of us technologically. That doesn't mean I want every ending to be happy rainbows and sunshine, but I want your choices to matter in the ending, if you took your time and did everything right, and had the galaxy on your side, you should be able to win, and not take out the Reapers while screwing over the galaxy, and killing off Sheperd in the process.
Don't get me wrong, I enjoyed the heck out of every second of the first two games, and everything except the last five minutes of the third. Hell right at the end with Anderson had me in tears, in a good way, unlike a few minutes later, which was in a bad way. And the third, up until that point was the best game I've ever played, every moment with your crew, with your love interest, the combat, everything was pitch perfect. Everything I ever hoped it to be. Which I guess is why the ending feels so wrong.
I feel kind of silly for being so upset about this, I mean it is just a game after all, but I've never put so much emotional capital in any other piece of fiction before, I played 1 & 2 so much, and waited for this game with bated breath, and I think part of the reason it does feel so bad, is that my Sheperd wasn't just another character in a game, or movie, or TV show, but she is a small representation of me, which makes these games have a greater impact. And to feel like I was robbed of the proper ending just well, sucks. I hope they fix this so I can look at, and play these games with the same wonderment I had for them just 2 days ago, and not the bitter disappointment of the last 5 minutes of the series.
I guess to sum up this blob, I'm praying for DLC, and pretending that the ending never happened.
