These characters (and Susan) were chosen to play this game via poll, and I've written around that. I'm sure I could have made any group of characters work somehow (if for no other reason than being able to cheat via fourth wall breakage), but these four characters present several opportunities that would otherwise just not be available, so I'm pretty thrilled.

The fact that Rhoda's involved makes it extra good that this is blatantly non-canon and includes fourth wall breaks, however, because Susan's never met her in canon. This way, there doesn't have to be any sort of proper introduction, and that can be saved for an actual canon story.

I'm ALSO thrilled that Diane lost. Don't get me wrong, I would like her in a story like this, but there was no way Susan wasn't going to be among the four (she was a VERY popular choice), and not only would them being in this story together before meeting in canon be weird, but, well... We still haven't sorted out if / how closely they're actually related to one another, and there's literally an attraction mechanic in the game I've designed. There conceivably could have been a few issues, there.
