Ubisoft has stressed that the impressive Assassin's Creed III has only been made possible due to the annualised release of the franchise.
Some critics had attacked the publisher's decision to elongate the Assassin's Creed II world with two subsequent console releases – Brotherhood and Revelations.
"We have multiple groups now working [on the series]. We started this one in January 2010, the same time as Brotherhood and before Revelations," creative director Alex Hutchinson told Eurogamer.
"The core team on this one has been working at it for almost three years, which is something you can almost never get in the industry these days – it's too expensive, too risky.
So we need the other projects to support that kind of development – these big jumps.”
Hutchinson, when questioned, remained coy about whether of not ACIII will get the same kind of annualised treatment in 2013 and the years ahead.
"I think we've become much better at planning forward in the franchise so we have ideas," he stated.
"But we also know players love new characters and radical changes so we're still figuring a few things out. I don't know. I think it would be kind of neat at some point to say 'Connor is a character, he lived in this big epic game, that's his story', instead of trying to drag it out too much.
"But then again, it took up 18 months in terms of casting actors, building 20 or 30 versions of the outfit... just working on all these things to get it right, so it's not something you can do quickly."
