You know I have my questions on this as well, cuz Sandal's prophecy seems pretty close to what Solas is attempting to do. "One Day the Magic will come back - all of it. Everyone will be just as they were. The shadows will part and the skies will open wide. When he rises everyone will see". Combined with the fact that there is a theory that Hawke was meant to be a returning PC for DA:I before DA2 got iffy reviews and the fact that the Inquisitor does seem to deal with a lot of events that Hawke helped start (Mage Rebellion/Cory), I'm kind of wondering just how much of Inquisitions content was based around the events of 2?
If they really did plan this far ahead (at least some sort of basic degree) I'd be darned impressed. Though that may imply DA4 being part of this overarching story as well and perhaps will contain far bigger events in regards to Thedas than we initially thought. Not sure what I think about that...
Well, they probably had basics going since the beginning. My thought is that the expansion that got cancelled, Exalted Marches, would have handled a lot of what then went into DAI. I suspect we would have seen Hawke dealing with the fallout from Kirkwall at that point in the form of the mage templar war.
They've never told us exactly what was going in from Marches, but I wouldn't be surprised if their timeline got royally putzed with having to expand the third game to deal with all the things that would have been dealt with in an xpac.
Funny story I heard back when I got into Babylon 5. The creator was a friend of Harlan Ellison, and tells this story where Ellison would go to a bookstore and write a story, and he'd put each page up as he finished it. No editing, no second drafts, just the page, and he'd keep going until he finished. Joe Straczynski said writing and producing B5 was much the same since he had to correct for things like actors leaving the cast, an actress breaking her foot and not being able to film a fight scene (seriously) etc. If you're not familiar with Babylon 5 and like SCI FI, I recommend it, it's one of the first American TV shows that I've seen carry a story arc for five seasons. It was pretty much written as a five act play.
I think Dragon Age has become much the same thing. They had to course correct for those epilogue screens in DAO since they weren't sure they'd get a sequel and wanted to give some closure. Then whatever they had to do to edit the story back together without Marches. I can't imagine how herculean that was.
I'm certain they know the route they want to take, but if it looks exactly the same as what they *thought* it'd look like when they get there is the question.
I wouldn't be surprised however, if somebody did go back during writing and find that quote and go "hmm... Let's use this and screw with them so they start asking whether we meant this from the beginning or not."
