I have just about confirmed that some time early in the New Year (so after the Christmas Special) I will be helping run Propulsion, a 24-hour gaming marathon for charity here in Edinburgh.
And I just had a very daft idea.
Do a big multi-Doctor adventure for eight to twelve hours. Doctors and companions coming and going (yes, like Dimensions In Time, shut up) as players come and go.
Hmm. Will think on this further.
