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.
Q: 'What would a game look like if a UI designer designed it?'
A: 'A big button that says: "Click here to Win."
its dead and buried, at least for me, here in the southeast US.
