As far as we're aware, this is the single online interview Kojima's given ahead of the June launch of MGS4. We could news-ify it, but we won't. You should read it. A taste:
I've been trying to pass on the baton to my younger staff to create the series, but it was difficult, and I kind of look back and think that maybe this was the reason that it was difficult to say to the younger creators that they should keep on creating Metal Gear. For instance, motion capture – some other teams might have different units to do motion capture sessions. Some might have a totally different unit to write the motion capture script, maybe they might ask Hollywood to participate and things like that. But for Metal Gear Solid 4, I was doing all of this together, so it was easier for me to do it because I could think of the game design and which emotion would work best and things like that.
