The addition of a free camera also made it more difficult for players to judge the exact height and distance of platforms, making jumping puzzles more difficult. Some of the more linear 3D platformers, like Tork: Prehistoric Punk and Wario World used scripted cameras that allowed for minimal player control. Others with more open environments, such as Super Mario 64 and Banjo Kazooie, needed intelligent cameras that follow the players movements.[32] These intelligent cameras required the player to adjust the view at times when the view was obstructed, or simply not facing what the player needed to see.
