You know, it amazes me - although maybe it shouldn't - that the person taking this discussion with the highest degree of calm seems to be David Gaider himself. So many people seem upset by the very thought that people don't like the Leliana alive thing. Yet who's not upset by it? David Gaider. Or at least, his posts don't seem horrified and upset - I'm sure to some degree, he would prefer that everyone be happier with it.
I've read this whole thread - yes, even the posts I didn't make.

And I read all of David's responses. I chose this one to quote:

Picture you're reading a book, say, since I know you've read it, A Game of Thrones. Now say a major character who dies shows up in A Clash of Kings, perfectly OK. It appears the death didn't happen, their head is on their shoulders and none of the other characters seem to think anything is up. Now, I don't know about you, but that's just downright stupid. How would that be acceptable storytelling in any medium?
That depends on whether it's ever explained at all.
If it is, and I just don't like the explanation. then I rant for a while about stupid author perogative and how the story in my head was so much better... and when I calm down, I go back to reading. Or I don't. It's not a science.
I can't think of any film/book/play sequel or anything where a major character has DIED only for them to show up in the sequel with the events that caused their death never happening.
What never happened? Who said something never happened?
In any other medium it would be bad, not to mention lazy, storytelling, but because it's a game it gets a free pass? No, sorry, you don't. The story you've told me has terrible continuity. Oh? You say that it would make sense to some other people you told the story to? I don't care!
Sorry, but I'm not sure what you're talking about, here. Who said anything about a free pass? And who are these other people I told the story to? What?
And I do believe continuity in important, incidentally. That doesn't mean I'm not going to occasionally arrange events to happen the way I want them to (or need them to). If that means I don't consider some things sacred cows the way you do-- then I guess we're at an impasse. Sorry about that.
I highlighted his response to a hypothetical very much like the situation we have with Leliana. Character is killed, character is back, with no ill effects apparent. How does Mr. Gaider respond? He wants to see the explanation. Seems perfectly reasonable, to me. Seems like what a lot of people, myself included, are wondering - what is the explanation?
Now, I have said that this appears to be a retcon. That was before David Gaider ever posted in this thread, or any other that I saw, stating that there was an explanation. Okay, I have since changed my attitude - I now say it seems like a retcon to me, but I'm willing to see the explanation, and then decide if I like it.
And what did Mr. Gaider say he would do in this situation? Look for the explanation, decide if he liked it, and respond accordingly - continue reading (in the example given) or give it up. He also allowed for the possibility of ranting.
Why are we, fans of the DA series, not allowed the same? Why must we simply swallow this turn of events with no complaint? Why can't we ask if there is an explanation, and ask to see it?
Now, I understand Leliana is important to the series, in the view of the devs. That's fine - its their story, they SHOULD decide who's important. I understand they decided she was important enough to bring back, even though they gave the player the option to kill her. And yes, she was killed - her body fell, her body was looted, her body vanished, just like anyone else you kill. At least, it seemed we killed her. It seems there is an explanation.
All we're saying is, we want to hear it. I know that David Gaider is not going to post it here on this forum, nor is any other member of the DA team. I fully understand that. I hope to see it in some future installment of this series - DA3, some form of DLC, etc. Not seeing it will bother me. Not liking it will bother me. But you know what - David Gaider accepts that I - or others - may not like it. Why don't the rest of you?
