On Emergent Gaming & Player Choice (from this interview)
Kojima: First of all if you give somebody a mission, and say your mission is to go and rescue this person, already you create some drama there.

What I want to do is create a true open world experience. Where the player has all these options available to them and really limitless gameplay. That’s what I’m trying to accomplish with my next project, .”
