What I really like about Khan Academy is that Sal takes away all the magic. The limit as x approaches 0 of sinx/x isn't 1 because "that's the formula," it's because (insert Sal's 15 minute proof showing the graphs and allowing you to intuit the result).
In contrast, I just watched the first two lessons of this series and so far it feels like a lot of magic. It's just a "rule" of strictly dominated strategies that each of player 2's middle column values are larger than their end column values, so we can eliminate the whole column. Why is this? What do those values represent?
For anyone who has watched more of the videos, does the series improve in this regard?
When I started making the videos back in 2009, my concern was just showing how to solve games. Details were details, especially since your average YouTube viewer does not have much an attention spam that lasts past five minutes.
But you're right, the other things are important. I eventually get to them in some of the later (and longer) videos, I talk about them in the textbook. The first lesson is a free PDF on my academic website wjspaniel.wordpress.com, so you can check it out if you are interested.
I actually think this approach to game theory is better for the uninitiated trying to get their hands dirty with some fun problems in game theory without needing the math or economic background. He doesn't go very in depth with the proofs but those aren't really needed. Most of the examples he gives are more fun mental exercises that have to be talked and reasoned through, which really is the essence of game theory. Once you have that understanding of backwards induction, it's then much easier to move into the more complex problems (dynamic, incomplete, asymmetric information).
To be able to grasp a problem like pirates after watching a few videos is very cool and much more practical, where the Yale course jumps directly into Cournot/Bertrand games after five lectures. If you have no prior knowledge of economics, it would be much harder to visualize things like competition and marginal cost in this context. This online course is really just a primer for bigger topics.
Wow, this is a nice effort Mr Willian Spaniel did here. I just watched some classes, and they are very nice spoken and clear. It's just like Khan Academy!
But the most impressive is the textbook costs, only 99 cents or 2,99 cents! I think I will buy, watch the classes and wait for the stanford free class to make a better foundation in game theory.
Stanford will be continuing its tradition with online courses this spring and one of the classes they plan to host is an introduction to game theory: http://www.game-theory-class.org/index.php .
I was not logged in to Amazon when I first checked the links. The prices when not logged in were 2.99 and 4.99. When I logged in, the prices became .99 and 2.99.
Game theory doesn't become computationally intensive until you reach mixed strategies, which start about half way through the first chapter. (If this comment is referring to the PDF preview on my website, the PDF only contains the first lesson.)

Thanks for the feedback.

The Yale Open Courses Game Theory class is also worth checking out. Material is taught in a very accessible manner.

If you skip classes to work on your side project, that web site is must see.
