I'm a fan. I've been Netflixing my way through them chronologically. I'm almost up to the point that got me hooked as a kid: I've started the Tom Baker years. Already seen every episode for the 9th and 10th doctors. A few years ago, BBC publishing put out a long run of books (may still be going on, but they don't seem to be coming to the States if so), half of them featuring the first seven incarnations and half featuring the only-from-the-TV-movie 8th docotor. I have probably 60 or 70 of those, but have only made time to read a couple.
It sounds, though, like the game is neither licensed nor very stable. In high school I wrote a series of four Doctor Who "games" (not IF) which were pretty bad, and I've come to realize that that type of thing is better left to people who are actually authorized to do it.
I don't see a listing for this on the IFDB. Is there a website?
