Doctor Who is about to take his TARDIS into PC gaming once again. BBC Worldwide has announced plans to launch a free-to-play MMO based on the long running sci-fi TV series. The game itself is titled Doctor Who Worlds In Time and is being developed by Three Rings, best known for their MMO title Yohoho Puzzle Pirates.

Details of the game are scarce but the official press release states that Doctor Who Worlds In Time will let players "follow in the footsteps of the eccentric and brilliant Doctor by travelling through time and space, exploring new worlds and encountering many alien races, both friend and foe." The game will launch sometime later in 2011.

In 2010 the BBC and developer Sumo Digital released a four episode downloadable PC game series, Doctor Who: The Adventure Games. A second "season" of the adventure game series is slated for release later in 2011.
