gota start somewhere. why can't flocking and game theory be part of psychohistory? I always thought of psychohistory as mathematical calculations on crowds, statistics of large groups of people. Flocking and game theory would naturally be a part of it, maybe the basics, or one branch. But, I read Foundation many years ago, so maybe I'm just remembering more to it.

Play the game Foundation on Steam and you can see how the evolution of a society really flows, including the resouce production supply chains.
