The First Adventure (video game)

Doctor Who: The First Adventure was the first officially licensed Doctor Who video game, released in Autumn1983 on the BBC Micro.

The Fifth Doctor makes his way through four different stages, each a Who-themed variation of then-popular arcade games, including Pac-Man, Frogger, Space Invaders and Battleship.

While this was the first licensed Doctor Who video game, it was shortly preceeded by Doctor Who Adventure. BBC Software soon followed up with Doctor Who and the Warlord.
