This is cool
Wired has an article about the return of the choose your own adventure format. And the article itself is in choose your own adventure format.
I read several choose your own adventure books when growing up. (For example, I remember the name "Turtalia"; Google it and see what you find!) I would read each book to try to find all the scenes and all the endings. I preferred books with some bad endings and some good endings, rather than ones that would eventually reach the end, no matter what you did. And I absolutely hated books that talked about "you" without establishing that "you" were a character in the novel. A phrase like "You can't wait to get home and see your pet dog" is just wrong if you don't have a pet dog!
Amusingly, these books are about the only time one will see writing in second person format.
