This is a great concept for running an RPG adventure solo. Depending on the effort you want to put into it, this can run anything from a mini-delve to a major on-going campaign. You can run it all with the help of this book.
However for it to work properly it requires a good amount of effort, ingenuity and recording. The book points you in the right direction but you have to interpret the details yourself.
A very ingenuous system.
