He so badly wants to be done with the series, he recently told 1UP: "I have three concepts for MGS5 already. What would be ideal for me with MGS5, though, is that we don't do those. If the team picks one of those concepts, I have to get involved again, which I don't want to do."
Could someone please come up with an insane enough plot for MGS5 so Kojima can hurry up and make us another Snatcher game? Who's up to the challenge? Is Ted Kaczynski still working?
