Metal Gear Solid 5: The Phantom Pain is the first of the series to go open world, which seems like a natural progression for the long-running franchise. But the inspiration for that move came from an unexpected place: tablet devices. Series creator Hideo Kojima said that he made the decision to make a Metal Gear Solid sandbox when he was thinking through the ramifications of a second screen at play.
"All the freedom is up to you and there are no rules [like] the linear games in the past," Kojima told Official PlayStation Magazine UK. "You can use smartphones and tablets to interact with the world. That's why we did an open world, because we thought about all these interactions on multiple devices."
He also noted that the tablet functionality will be important for the announced user-generated content. "Using tablets and smartphones you can also enjoy MGS V and create user-generated missions within the world," he said.
