Less then 66 days until Mass Effect 3 comes out, cant' wait.

Looks like you will need to start at the assault on the C. Base to experience the extended ending: http://masseffect.bioware.com/about/extended_cut/.

So probably about an hour and a half-ish?

I just played from the final save and you still do get the new endings. That's just not the full extent of what was added is all, since some plot holes get filled in before the last few minutes.

IMO, it still doesn't really "fix" the lack of influence that previous decisions have, but otherwise makes things good. Not perfect, but good. Adding the refusal choice was a nice touch. It's an even more abrupt, in some ways down ending...but it gives that "Shepard wouldn't do any of this" option, and keeps some speculation going.

See, I really like the futility of the endings. You spend all game building up this force and battling the Reapers and in the end... you fail. Your coalition is no match for a force of synthetics who have had millions of years to perfect their craft. But you are given one last chance. Which leads to the question: which is more important, your pride, or the sentient races of the galaxy?
