Endless Quest books
This was TSR's version of the Choose you own adventure (CYOA) books, based on Dungeons and Dragons. The Endless Quest books were longer and more involved then the CYOA series but nonetheless the same principal. As you read the story you turn to different pages based on what you choose the character to do. Several endings are always possible, some leading to your death. I used to love these books as a kid. The Vertigo comic series Unwritten featured a CYOA type story in issue 17. It would be cool if more comics featured this.
