I can't believe people are happy about this change. So much of Big Boss's character was revealed in optional codec calls throughout MGS3, like his fear of vampires and weird need to eat everything. Same for the supporting cast. Paramedic's interest in cloning was in an optional codec, and so was pretty everything we know about Zero. Peace Walker and MGS4 suffered in world building and character with the removal of context sensitive codec calls, and its a shame TPP is moving in direction of Kaz shouting in your when you look at things.
