Metal Gear Solid V: Phantom Pain's open world has some limitations

Metal Gear Informer reported on the 26th episode of Kojima Station, where the director himself told more about Phantom Pain's open world. Kojima mentioned in the Japanese program, that you can roam the world freely with the exception of one limitation. If you accept a mission, you can't leave the mission area. Otherwise you will fail it automatically.

This doesn't sound so different from other open world games, as some of them have already employ similar systems. Hopefully the areas will be large enough to accommodate for different ways of tackling the missions.
