Doctor Who: The Game of Time & Space was a 1980 tabletop game set in the Doctor Who universe, designed by Derek Carver for Games Workshop. It was one of the earliest Doctor Who role-playing games.
The game is "for 2-6 players, 8 years and over". Gameplay used a board, which is divided into 60 "zones", as well as 76 Alien counters, 76 Scientific Item counters, 36 Key Mission counters, 95 Key Part counters, 6 Doctor Who Alien & Item files, 6 pawns, a twelve-sided die, and a rules booklet.
The Fourth Doctor and Sara Jane must race through the universe looking for the scattered fragments of the Key to Time, scattered across seventy planets. They must not only evade the dangers to be faced on these planets, but three old foes of the Doctor who seek to acquire the Key for themselves, as well as the Doctor's previous incarnations and their own companions, who are all seeking the Key in their own right and may end up interfering with his own efforts. Can the Doctor get the Key and get back to the Domain of the Time Lords on Gallifrey for the hero's welcome he deserves?
This story may constitute one of the earliest known narratives where Liz Shaw is travelling with the Third Doctor as a conventional companion in his TARDIS (whereas her televised era took place entirely within the Doctor's exile on Earth).
According to one account, the Master had the appearance of Roger Delgado while on Gallifrey. According to another, he had Anthony Ainley's likeness. According to another one, the one with James Dreyfus's appearance was the incarnation who ran away from Gallifrey.
While fighting to extend his life at the end of his regeneration cycle, many bodies were possessed by the Beevers incarnation, but all kept somehow reverting to his real being until he finally regenerated into the MacQueen one. Hence, these sections cannot be strictly chronological
