Ahh the excellent Earthsearcvh by James Follet.
Earthsearch I then II then Earthsearch Mindwarp.
I need to seek out this 7th Dimension.
Most of the radio plays I listen to are from the 40s,50s.
I really love Dimension X and also the incredibly scary "Lights Out".
As a huge audio drama fanatic I am pretty impressed by the numbers of people here who do listen to them. The result of the poll is much more encouraging than I would have suspected.
Well the Earthsearch Mindwarp audio serial was produced by Big Finish, I believe.
And, starting on Friday at 6pm they are re-running the excellent "Architects of History", which is a 7th Doctor story about what happens when The Doctor accidentally lets a **** scientist (really? the forum is censoring the use of that word? *sigh* fine "a ww2 german military personage"... jeez, when did we start censoring historical facts?) run off with the Tardis. It is one of the best stories Big Finish have ever produced. On iPlayer, you can catch some of the episodes that lead up to it, but Architects is the best.
Big Finish did some of the Blake's 7 audio dramas (along with the BBC). Well worth a listen, they are.
I have a lot of big finish titles but found that a great deal were poorly written and the stories were very average so I stopped the "main range". They have some excellent ones though like Jago and Litefoot. As for 7th Doctor stories those are some I steer away from completely but I will have a look at the one you suggested. I also steer away from anything written by Nicholas Briggs if I can I don't find him to be a good writer I'm afraid, no disrespect to him as he is excellent in the other things he does, just not a fan of his writing.
