Originally, the overarching storyline in Assassin's Creed was supposed to end.
But it's not gonna. Not now, anyway.
Last year, Assassin's Creed IV: Black Flag director Ashraf Ismail said that his team had an outline for the franchise, and that outline did include a final climax. But as Black Flag lead writer Darby McDevitt told Edge , in fact, that's "not exactly true." Rather, this ongoing plot is akin to "Dr. Who."
"There's been a bit of confusion in that [Ismail] once said that Assassin's Creed has an ending–that's not exactly true."
McDevitt said there will be individual endings for each installment, "because all of history is open to us." With so many possibilities, the writers don't intend to "definitely end the universe." Initially, the writers encountered a problem: Back in 2007 when the original title came out, they had a plot where Abstergo would launch a satellite that controlled people's minds. But when the series took off, this idea hit a snag:
"That unfortunately took a back seat in ACII when they swapped the plot point for the end of the world, which was conveniently going to happen in the same month in 2012. This was a hard date we were going to hit–we realised very quickly that Assassin’s Creed is a popular franchise and we’d like to keep it going."
Well, we don't want an ending. Just keep the franchise going and bring us to all sorts of memorable, enchanting settings!
