I never know how to feel about such great attention to detail, it's very very cool but so easily missable or trivial in how it affects core gameplay most of the time, it can feel a little pointless. It makes me appreciate a game more if the game and its main design are great without it which fortunately MGS3 is. As for MGS4 and the others post-MGS3, stuff like this didn't make me appreciate the game much more.
