I don't think that Kojima aims for realism in his games. Personally, I don't like realistic games anyway. If I wanted absolute realism, I'd just go outside. Only one life and no continues, ohh yeah.
I look for realism in modern games, graphics, etc etc. Of course unless the title is "fantasy" or "fiction" Games are some place between reality and fiction i understand that but I dont like the cammo. That is all Im saying.
