7. Trapped In A Video Game
For number seven, I am throwing out a slightly different idea; the Doctor and his companion(s) being inside a video game. Its not like he hasnt been playing someones game before - The Celestial Toymaker and The Game of Rassilon were both games and trials - but now with the love of the virtual worlds that video games have, and the lack of an as yet actually, properly decent Doctor Who video game - The Adventure Games and The Eternity Clock were average at best - a televised episode would be perfect to base a game on.
