I've written a lot about Mass Effect 3 in the last few weeks. Suffice it to say, I'm a fan of the game and don't feel the slightest bit "betrayed" by it, though I do think some (not all) of the concerns many players have with the endings are indeed valid criticism, and I understand deeply why there's so much emotion tied up in the criticism as well.
Here's a brief round-up of the interesting things I've had to say about the game so far:
Review: based on a very fast, default-Shep playthrough; it had to be ready to go into the world at midnight on launch day. And it was still a great game.
I also got to make a cool gallery of some of the voice actors, and my co-worker Chris made a video I love out of the screenshots I took from my Shep's game (contains spoilers).
And then there's the piece I'm most glad I wrote (spoilers, obvs), Why Mass Effect 3's Ending Doesn't Need Changing. And if I'm being strictly honest (eeeeeeeeeeeeee) this tweet about that piece, from a certain Jennifer Hale, made my week.

EDIT Afternoon March 24: I have deleted all comments and locked the post. The discussion, such as it was, was circular, uncivil, and unproductive. For readers wishing to discuss the merits of the game itself, see previous ME3 post.
