That's not a bad idea, Remi. I was thinking of just doing a dice between the interested volunteers instead of the full group, then a role for the other roles with the remaining. Sadly, as GM, I can only play roles that know everything, so my options are either forensics or nothing. =(
But that's okay, I got to play a round with you guys, that's more than many GMs can do for games they run here or on CHWB.
