yogsloth: If there's a nightkill in night zero, that's just mean and lousy game design.
I considered running my Werewolf game with a "Night Zero" kill. I was actually going to leave it up to a "pre-game" vote - first to three votes would decide it (Do we start Day or Night?). I figured it would also be a good "spark" for Day One voting as people discussed who voted Day or Night and why.
My thought was that starting Day gives zero information, but full contingent of town; while Night would mean town would start down one, but the Seer would also have had a scan.
In the end I decided against it, but that was only because like 85% of the people who joined that game were new to Mafia, and I didn't want someone to be offed before they could even say a word in their first game LOL.
If I were to run another Werewolf, I'd probably do the Day / Night vote just to see it play out.
