Sorry, MarkB, but your analogy doesn't hold
The New Doctor Who came with a built-in reason for being able to contradict the previous stories. In fact, Doctor Who (original) came with a built-in mechanic: parallel universes. In one universe, Mars spawned the Ice Warriors. In another the Osirans. In another, the Fehndal. And bouncing between parallel universes was so easy that they never had to even mention it.
Where NuWho fell is that be making season-arcs, they anchored themselves in One universe, and when they contradicted themselves, they made a glaring discontinuity.
Big Finish and NuWho have had massive cross-pollination since the show began, including script and story ideas, writers, producers, and script editors.
Also, one of the delusions behind the 1996 Fox movie was that it would be a pilot for a new show/series reboot. Yet another way in which it utterly failed.

As for the RPG and how it will be affected: same as any RPG: use the rules you want, dismiss the ones you don't.

On another level, and yes, this is the pot calling the kettle black, can we please keep this civil and not devolve into personal attacks like bickering, squabbling children or CNN politicians?
