 The team made use of Havok 's Behavior toolset for character animation , which allows for a greater fluidity between the character 's movements of walking , running and sprinting , and also increases the efficiency of the third @-@ person camera option which had been criticized in Oblivion . The toolset allows interactions between the player and NPCs to take place in real @-@ time ; in Oblivion , when the player went to interact with an NPC , time would freeze and the camera would zoom in on the NPC 's face . In Skyrim , NPCs can move around and make body gestures while conversing with the player . Children are present in the game , and their presence is handled similarly as in Fallout 3 in that they cannot be harmed by the player in any way since depictions of violence involving children in video games is a controversial and largely @-@ debated issue . Skyrim makes use of the Radiant AI artificial intelligence system that was created for Oblivion , and it has been updated to allow NPCs to " do what they want under extra parameters " . The updated system allows for greater interaction between NPCs and their environments ; NPCs can perform tasks such as farming , milling and mining in the game world , and will react with each other .
