Branching Tree

The branching tree structure brought up by Chris Crawford(p.124) reminds me of the choose your own adventure books(CYOAB) I used to read as a child. When I first started this class, I immediately thought of these books as a perfect example of an interactive medium. Oh, how wrong I was.
The branching tree structure, used in the CYOABs, is little more than a story trying to get an extra mile out of a tank on E...better yet, since we are metaphoring* cars, a CYOAB is like having a learners permit; sure your driving around town, you can go left, you can go right, but in the end it is all up to your mom, sitting in the passenger seat, telling you exactly how far you an go. CYOABs only offered you so many possibilities, all of which were already predetermined, and lacked flexibility(just like a parent).
For full interactivity, there should never be an end; certainly not a clear one. If there must be an ending, let those possibilities be endless.
