The Assassin's Creed series has been a big hit for Ubisoft, and though the main trilogy of games has been completed, fans as well as critics have responded well to Assassin's creed 4: Black Flag. While some have questioned if Ubisoft has an overall story arc planned for the series, a new interview indicates that the company has no clear end in sight for the franchise.

The lead writer for Assassin's Creed: Revelations and Black Flag, Darby McDevitt, revealed that despite what some other Ubisoft employees may say about the ending of the series, the company does not have a set end for the franchise in place. Ubisoft sees the series like the long-running TV show "Doctor Who" instead, he said. 

"...There's been a bit of confusion in that [Black Flag game director Ashraf Ismail] once said that Assassin's Creed has an ending - that's not exactly true. This storyline has an ending, but because all of history is open to us we see the universe as a Doctor Who type thing. There are so many possibilities we don't want to definitively end the universe, but we can have storylines that have endings," McDevitt told Edge.

This makes sense given the wide open nature of the series and the ability of Ubisoft to pick a random point in history and set a game within it without too much difficulty. In addition, McDevitt also revealed that Ubisoft had a plan for the story of Desmond from beginning to end that they followed "75 to 80 percent of the time" but have since moved on to setting up a new modern day storyline for the series.

McDevitt made it clear that Ubisoft is not looking to tell another story in the form of a trilogy, because it may become prohibitive to the popularity and flexibility of the franchise.

"We've moved on from specifically defining when a story will end...The problem with the Desmond trilogy was that back in 2007 they set a date with Abstergo launching a satellite that was going to control people's minds. 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 realized very quickly that Assassin's Creed is a popular franchise and we'd like to keep it going," he added.
