I agree that you should split it up. At least two parts, maybe three depending on how long class periods are at your institution. I also found the slide were you list examples of territory a bit odd, given that you were showing pictures of objects rather than the objects themselves. Otherwise, it looks good.
Here is a presentation on the map and territory I'm planning on giving to my game theory class.
It's based on Liron's You Are A Brain post.
Any suggestions for improvements?
