KSD: "Codec calls have a special place within this structure as they represent the innermost sanctuary of Snake, our character. A codec call occurs on its own menu screen separate to the ‘action’ of the outer gameworld, which, as we might normally view it, would be the ‘real’ gameworld. It accentuates the values of the ‘real’ gameworld with respect to how Snake moves through and lives in the latter: shyly, diligently and safely. If you play MGS the way it suggests it should be played, you probably move Snake around coyly, gathering up information about the level and your enemies while guarding your position and minimizing your presence. You plan your route. You wait patiently."
