> There can only be more than 2 choices if children of the node are leaf nodes (endings). Huh? Lets say each node is a page, and the book is 256 pages. I don't see why the graph could be any (cyclic) or not graph? True, binary choices probably makes it easier to make an easy, and natural feeling narrative - but I don't see this as a hard limitation? I mean, in the extreme case (with one very long first page) you could have a "2-page" story with beginning, and 255 alternate endings? And you could modify that, so that 254 lead back to the first page, with an additional hint... [ed: See the map for "cup of death" for an actual book that uses "four road fork". It is curious that all of these concrete books seem to use binary choices. I can't remember the CYA books I read when I was a kid (Author, name of series) - but I seem to recall there was frequently three, four choices - often one or more choice would loop back (often literally, as in a path that forked around and led you back to an earlier fork in the road...).]
