Things to point out:
1. 1963 is the start of the series, the first appearance of the Daleks, and then in Sylvester McCoy's 1988 Remembrance of the Daleks saw the destruction of Skaro, the planet of the Daleks that will be visited in the game. Wonder if that will be referenced?
2. The Cybermen do not bear the "Cybus" logo on their chests. These may be "our universe" Cybermen.
3. While Charles Cecil and Revolution made Broken Sword 1-3, Sumo Digital made Broken Sword 4: The Angel of Death. So it'll definitely be an adventure game.
4. It has never been confirmed that they will be free (or available at all) to non-UK residents. The BBC has an obsession with denying people outside the UK their services, even non-programme stuff like trailers. Hopefully they will.
