i regret this setup. very much.
my inspiration was this game called "mostly mountainous":
http://forum.mafiascum.net/viewtopic.php?f=56&t=15655
it had this role that fate played called "town mole". it was pretty much greyice's role except it was town aligned and he pretty much had to bus all his partners before they killed him.
i thought, "what if i could have this role again, but not really have to artifically police what they said in the thread". so, i monkeyed with the win conditions to make it to where the mole had an incentive to not bus (while finding an even more informed minority). i also added in the two "detectives" who could help ferret out the don while WIFOMing him with their choices of who to interrogate (they also acted like a jailkeeper). sadly, greyice didn't seem to have much fun with the role, so i'm pretty sure i failed with this mechanic.
so, yeah, sorry everybody for this monstrosity of a game. if it's any consolation, this game convinced me that i shouldn't do anything else cute/experimental.
