I don't know your head or universe to try such a thing, but as a joke/tease I did write a chapter for a buddy while he was only halfway done writing it. I did good enough of a job that other then adding a couple lines he used it as was. (Why yes, me be crazy - it beats being sane! ;-) )
I've bought three versions of the RPG now and have yet to find a group of players who grok the setting.
I actually became aware of the comic by getting the (first) RPG.
I've never found anyone to play it with, but I have loved the setting (and the story) ever since.
So, no dinosaurs either...
"So, no dinosaurs either... " aside from birds, of course.
What are birds ? We just don't know...
@McThag @darkstripe I too, came to the comic via the RPG. It has long sat on my list of "I'd love to play this, but can't generate interest" games, sadly.
