Me and BLue have definitely felt that Kojima is making comments on society as a whole. He takes the reality of the world or how it could be and tries to break down that wall between reality and video game with little snippets of dialogue saying "This is reality, not some sort of video game."

Even the fact that the Metal Gear saga has been formed around specific events taking place in the past shows some other comments about the world in general, although these messages probably didn't start to surface until MGS in 1998.
