Hideo Kojima recently visited Australia to attend RTX Sydney.
He also took part in a couple of panels, including this one, a 'definitive interview' with Greg Miller from Pretty Funny Games.
It's a 90 minute, tell-all interview with the man himself and I recommend watching it.
Worth noting: Hideo Kojima has a really good translator. Normally these things can be pretty difficult to watch, but this is actually pretty well put together.
