SPA, it's a good question.
I don't know how the game's being played on other threads - and again, I'm not the moderator.
Here's what I do know: "Six Degrees of Separation from Kevin Bacon" was a drinking game we played in college in my day - while barhopping (legal age then was 18 BTW; later 19 ... fortunately NY didn't change it to 21 until after I'd turned 21 )

That is what I had in mind when I suggested 6 degrees of separation fron Scott - and it is the way it was played on the board where I first noticed it - last week. "Fellow cast members" is the premise on which I proposed this game to razzle - and the way I tried to describe it on page 1.

It seems to me: either razzle can make the call or everyone can vote on cast vs. cast and crew vs. cast plus directors & writers, et cetera........
