Welcome, Brian Cohen! You're reading a lot of interesting stuff... stuff I wish I had time to try.
Recently there's been a rebellion against Nash equilibria in favor of 'correlated equilibria', which are more computable but also, some claim, a more realistic model of rational behavior. The first paper is this:
* Robert Aumann, Correlated equilibrium as an expression of Bayesian rationality, _Econometrica_ **55** (1987), 1-18.
A quick intro to the main idea is here:
* Wikipedia, [Correlated equilibrium](https://en.wikipedia.org/wiki/Correlated_equilibrium).
Here's something I wrote, with a link to a nice article:
* John Baez, [Correlated equilibria in game theory](https://johncarlosbaez.wordpress.com/2017/07/24/correlated-equilibria-in-game-theory/), _Azimuth_, 24 August 2017.
I wish I had more time to think about this: I have a feeling it could be important!
