Choose Your Own Adventure (cyoa) books were very popular for people my age growing up. I recall spending hours going back and forth through various trees of decisions all the while fending off the carnal urges of cheating by reading all the endings at once.
A designer chap by the name of Christian has beautifully shown all that there is behind CYOA novels. It’s a hefty read text wise, so I would strongly encourage you to put aside some time for his discussion on the subject. Alternatively you can view his wonderful infographics.
Phenomenal. A brilliant example of why the internet is so awesome.
