I've recently got into the Big Finish range after the ones they gave away last year for the 50th. But I've managed to get myself a little overwhelmed. How much crossover is there between the different Doctors? Things like the Dalek Empire set-up and Zagreus seems to suggest that you need to be listening to them all but skimming this thread (in fear of spoilers) it seems you can concentrate on one Doctor and worry about the rest later. Because out of what I've heard I'd quite like to concentrate on either 6/Evelyn or 8/Charlie for now.
