I've been thinking about a Doctor Who RPG for a while, one that stays true to the spirit of the series, rather than a piece of generic rubbish with a Doctor Who veneer glossed over the surface.
So, when I found this link I was interested.
I don't know if it's the first Doctor Who RPG, or if it's just an early one, but the fact that it's now freely downloadable for personal use makes it a great starting point for exploring systems and settings within the universe of our favourite Gallefreyan.
I haven't thoroughly delved into it yet (or the free expansion), but I plan to shortly.
Perhaps there will be a time travelling FUBAR expansion on its way.
