Another update. Because running 40 copies of Jnes and seeing the same CPU load (although 40 copies of Zelda with the sound desyned is a bit odd) made me think about this:

From Joystiq:

The New Gamer has a fascinating video, with analysis, of the "averaged gameplay" of fifteen different gamers playing through level one of the classic shmup, Gradius. Why Gradius? Because it's "an auto-scrolling shoot'em up, is programmed so that the stage automatically scrolls at a fixed rate. With the stage constant, that allows us to compare how the player interacts with the AI and how, retroactively, the AI responds to that."

Averaging Gradius

I saw this movie a year or so back and found it fascinating.
