Create Your Own Adventure
From IFWiki
The Create Your Own Adventure site, hosted by popular web/wiki hosting service Editthis.info, contains Choose Your Own Adventure games that users can play, and registered users can modify. The games can all be played in a web browser, and the site is entirely MediaWiki-based, including the games themselves. The games are divided into categories; mostly by content (G, PG, PG-13, R, X) and includes bonus sections, such as games that are considered quizzes, as opposed to the standard CYOA format.
