I think it's interesting that people who make games often don't think of their players as basically a giant parallel computer. You're essentially sending a puzzle off to hundreds, thousands, or millions of 'cores' that will through a combination of brute force, intelligence, and a complicated but large network of communication, come to an optimal solution in a time span you as an individual probably can't even comprehend. They will not only solve your puzzle, but they will solve for how to solve it and then spread that knowledge.

Thus I found it hilarious when Blizzard thought it would take people months to completely finish Diablo 3. Real time? A week or two.
