OK, so let’s start with the basics. This is the first game we’ve played in a while with no third-party elements at all. That simplifies analysis of the game situation.
There are 22 players in this game, 17 townies and 5 scum. Ignoring all powers for a moment, we would have five "safe’ mislynches (lynches of Townies); the sixth mislynch would result in a loss.
There are two putatively pro-Town killing elements. By my figures (and someone else feel free to tell me if I’m wrong), a Vig has to maintain a 1:1 ratio of scum to Townies killed just to break even. In other words, if a Vig kills at Night, and alternates between Town and Scum kills, we will have the same number of mislynches (6) before we lose. If the Vig kills more Town than Scum, no matter how many Scum he actually kills, our number of allowable mislynches will decrease. Of course, we gain advantage from Vig kills - we get more information for analysis - but this is worth remembering for both of our Vigs, who both are evidently optional, not mandatory, Vigs.
Neither the politician nor John Connor will affect the mislynch situation. Sarah Connor won’t either, but if she’s alive on Day Six, most of our living power roles will probably not have their powers anymore.
The Commuter probably can buy us half a mislynch. The doctors should earn us a half mislynch between them.
The Jester scum will probably be lynched before there are 12 people left. We have to recognize that, and be prepared for recruitment. Lynching the Jester, simply put, will count as a mislynch, because the result will be the same - after the lynch, the number of scum will stay the same and the number of Townies will decrease by one. Thus the Jester balances out the Commuter + the Doctors.
The role blocker and bus driver, might net us half a misynch between them, if they play very well.
Which leaves us back at about five safe mislynches and six to lose.
Except for the T-1000.
The thing is, if the T-1000 manages to mimic either of our Vigilantes, thus earning a bonus Night kill, we’re in deep shit. Three bonus scum Night kills cuts our allowable mislynches in half.
