The thing with Kojima is that he very quickly developed a 'frustrated movie director' streak, the later Metal Gear Solid games are incredibly overblown and have far too many overly long cutscenes, ridiculous plot twists and even the fourth wall breaking elements grated after a while. I'm all for complex plots in my games, but I do draw the line when the game feels that delivering it's plot is more important than giving the player a game to play.
