I see lots of speculation about the endings. Some think they intentionally made them bad, so they can sell a Broken Steel type dlc.
Some people are looking at the endings in detail. http://www.youtube.com/watch?v=ynYgr1rqEec
Reminds me of arrival.
OK- let's nip this in the bud and not turn this into the cesspit of angry fans on the bioware forums. They did not INTENTIONALLY make the ending bad. That kind of statement is insulting to game developers everywhere, not just the hardworking folks at Bioware. I'm sorry, but that's just flat out a wrong thing to say. Let's show gaming culture in a better light please, and keep a bit of sensible perspective.
I personally was
disappointed with the ending I got from a logic perspective,and from a personal note. Do I think they could have made a tighter ending to the game that would at least have given me a better sense of closure for my character and the crew I actually mostly cared about? Sure. There were contradictions abounding and some loose threads that fall squarely on whoever was making the final story/writing decisions. Apparently the loss of Drew Kapyshyn (sp?) hurt them more than they realized, or else there was just not a single strong voice pulling the writing together at the end of the day. It happens. The ending wasn't what I had hoped in some respects, but it wasn't a huge shock either, given the sad/anxious tone of this last outing from the get go.
But stop with these kinds of accusations - seriously, it's insulting to hardworking people and it reflects poorly on serious gaming fans like so many of you here (including me.)
And to clarify - Bethesda developed FO3
with an ending. It had a definitive "Game over" after the main quest -
something they were very clear about long before the game was released. They only did Broken Steel after the backlash, it was not planned that way from the get go. I for one was not particularly impressed that they caved over it, but I understand - their reasoning being that half the new fans brought into the game were also ES fans, and they were used to the ES style of open-ended games. And from their perspective, it does open up the game for easier insertion of any random DLC.
Consider this:
Spoiler The message said to continue adventures. The word continue emphasizes post story. How can we do that with mass relays destroyed? Alternate endings are the only justifiable way to continue post ending, otherwise there will be more plot-holes in this swiss-cheesed game.
"Continue" does not emphasize post-story. I hit okay, and it sets you back to the save just after you finish Cronos. So presumably you can continue trying to find more war assets and whatnot.

With DLC added, it would just probably add to available places you could go for this mission or that one before heading back to earth for the final run should you choose to continue with an existing save game.
