http://www.useit.com/alertbox/981115.html http://www.useit.com/alertbox/981115.html Ten years old, but apparently still relevant. Best part, the part I always remember: Note that 3D works for games because the user does not want to accomplish any goals beyond being entertained. It would be trivial to design a better interface than DOOM if the goal was to kill the bad guys as quickly as possible: give me a 2D map of the area with icons for enemy troops and let me drop bombs on them by clicking the icons. Presto: game over in a few seconds and the good guys win every time. That's the design you want if you are the Pentagon, but it makes for a boring game.
