Speaking with investors on the company's fiscal year results call today, Ubisoft CEO Yves Guillemot was very obviously pleased with how Assassin's Creed has performed to date, and defended its expansion beyond the originally-planned trilogy.
"What is impressive with the release year after year of Assassin's Creed is our ability to deliver every time with a high level of innovation and creativity in a large and very diverse open world," he said. "There is no other open world console game that is coming on a yearly basis."
Guillemot is so enamored with Assassin's Creed's success that he intends to apply the development model to other Ubisoft franchises.
"We are applying the very [same] product template to our other strong franchises to bring them back to Assassin's Creed blockbuster profitable status," he said.
Activision and EA have in the past come under fire for yearly iterations on their titles, mainly Call of Duty and sports titles. Widespread criticism and cynicism hasn't stopped these titles from being consistently strong sellers, however, so it's natural that Ubisoft wants to be a part of this kind of business model.
