May I suggest that, for the next game, we do a simple scumhunt setup, with 7 villagers and 2-3 mafiosos?
To me, it's more fun this way because, instead of pointing our way towards the culprit using simple logic (cop) and failsafes (doctor), we turn on each other and accuse one another simply because of outside-game influence and a bunch of reverse-psychology bullstuff floods the room.
