This game is totally unrelated to the previously released Doctor Who RPG by FASA, having different and simpler mechanics that often seemed arbitrary.

A later on-line supplement, "Timelord: Journeys", written by Nathaniel Torson, provided a system for creating original player characters.

The game includes many skills which are especially appropriate to the tone of Doctor Who, such as cheat death and macguffin.

The original game book includes extensive biographical information on all the companions of the TV series, as well as many of the villains.

In the electronic version, the adventure The Templar Throne has been replaced with another campaign, The Curse of the Cyclops.
