Series creator Hideo Kojima apparently has some ulterior motives for bringing Metal Gear Solid 5: The Phantom Pain into an open-world environment. He wants to incorporate mobile devices into the MGS5 experience, along with user-created content.
"The first reason why I wanted to go open-world is because I wanted to create a world that had a lot of freedom and allowed users to create their own gameplay," Kojima told CVG. "The other reason for the game going open-world is that we wanted to use multiple devices for this game. So using tablets and smart phones you can also enjoy MGS5 and create user-generated missions within the world. That's another reason we had to go open-world--if it was linear we wouldn't be able to do that."
He didn't offer any details on how exactly how the content will be created or how the game would meld with mobile.
