The Call of Duty: Modern Warfare series was a seminal moment for both the series and gaming in general. Despite this, Infinity Ward executive producer Mark Rubin indicated that the studio was eager to do something new with the next entry in the franchise.
“[It was] not a hard decision, but a long decision. When we finished Modern Warfare 3, we had this big brainstorming session that lasted for weeks. We all really knew we wanted to continue making Call of Duty. We wanted to create a new universe, or a new story at least. We wanted new characters and new experiences,” said Rubin. “The easy thing would have been – as we had finished the arc of Modern Warfare 1, 2 and 3 – to start a new arc within that same universe. That was the first step. But due to a lot of the changes we wanted to make with this new world, it really dictated out that we needed to make something that wasn’t Modern Warfare.”
“From a gameplay standpoint, we never felt hindered by the generation or the consoles or the tech,” added Rubin. “We always felt gameplay isn’t tech-dependant necessarily. But this new tech allows us to make those worlds that we are playing in more realistic. We always try to make it so the player always feels naturally involved in the world around them. The more realistic and natural the environment, the more the player’s imagination melds with that game.”
