In fact, what storyteller said could even be strengthened further. He said that he has no more information than anyone else, but in fact, he has strictly less information than anyone else in the game. Everyone else knows their own alignment and also knows that storyteller is Town, but storyteller himself only knows his own alignment.
And, of course, at least one player knows a lot more than storyteller, but that player probably isn’t going to be too helpful.
All that said, though, at LyLo, it really does make sense for Town to all follow the Mason. If Town is split, then Scum can switch at the last moment to force a mislynch and win the game, so Town absolutely must not be split at LyLo. And the easiest way to ensure that is for everyone to follow the Mason. The catch, of course, is that we don’t know if we actually are at LyLo or not.
Where it gets really interesting is in something like Pleonast’s Munchkin ruleset: In that game, everyone had a Watching power, in addition to other powers which could be used on other players (some beneficial, some harmful). So you’d have “I saw you take a nonmagical action targeting Bob. I think you were stealing from him.” “No, I was just using my own watching power on him, and saw him do something to Joe.”
The relative power of a single watcher scales in proportion to the number of other night actors. They can be as powerful as a doctor since they are a significant deterrent to NK’s on claimed power roles.
Possibly more so, based on what happens in the unclaimed situation. In most cases, it’s better to learn the identity of one Scum (if the watcher does happen to watch the victim) than it is to prevent one Night-kill (if the doctor happens to protect the victim). Plus he can sometimes help verify other power-role claims.
Interesting… for those of you following at home at T minus half an hour, neither Chipacabra nor Inner Stickler are currently logged on; if story votes for Guiri, it will likely create a tie.
