Re: Anybody out there playing Doctor Who Hero?
Well, that's entirely in keeping with the show. The TARDIS is as much a plot device as anything, and we've seen it equipped with features such as the HADS (Hostile Actions Displacement System) that causes it to dematerialise and rematerialise elsewhere if attacked... and then another writer decides to forget about that, or get rid of it or whatever, and we see the likes of Torchwood carting the ship off on a truck. The current series has shown us very little of the TARDIS interior, so its present options and abilities are largely unknown. I tend to think of it not so much like a series of rooms but more like a university campus, with courtyards and so on (heavily influenced by Shadis and the Cloister Room, I suspect).
The present series also addresses the "companion problem" to a degree, since Rose is an attempt to make a more resourceful companion than many of those who journeyed with the Doctor before her, but it's still a key problem with playing any Doctor Who game.
Series finale next week, after a nail-biting cliffhanger last night!
