I did a similar game here: https://forums.totalwar.org/vb/showthread.php?t=119908


I took over the minds of my players (one random player per night) and had to avoid being lynched. When I had inhabited the minds of all my living players, they lost. I could not murder, and the only deaths happened when the vote was tied; otherwise the lynch wouldn't even be lethal, it would serve like an investigation. The lynch was only lethal to the Snatcher.

So very neat idea, I thought so anyway.
