in this interest of hopefully stirring up discussion i'll somewhat oblige i guess.
I expect certain players to act a certain way as one alignment and slightly differently as the other alignment. for some players i think they do a better job of staying consistent in their "town range" so to speak at the beginning but become more "obvious" as the game goes and as their reads start becoming inconsistent/not making sense. other players are more inconsistent in the sense that whether consciously or unconsciously they do something different because they have game knowledge that they know they must have.
Other times I look at the decisions people make and decide if those decisions and behaviors make sense in the context of the game and in terms of win condition. For the last game I would say that more or less m2h's play didn't make sense for me in terms of trying to advance a town win condition.
i hope i didnt give too much away xd
