But then again there's a chance that you guys might not catch on so
What is the purpose for solving the theme as a group for town? We benifit by understanding all past lynches and future lynches. But on day 1, solving the theme gives no immediate benifit other than person PR benifits.
But what about mafia? Understand that I believe strongly of what OS has said about rule 13 from the beginning. They will have no private communication in the beggining of the game. Which means that they have to solve their present in order to gain these basic powers. In general I would like to prevent mafia from gaining their private communication as long as possible, but eventually town will have to solve the theme.
So like I was saying, Pros/Cons of revealing the theme day 1:
Pro - Town gets closer to gaining full powers
All FUTURE lynches would be revealed when flipped.
Con - Mafia gets closer to gaining full powers
Mafia gets closer to gaining REGULAR powers.
Why would we not wait until day 2 to understand theme? The benifit that mafia gain by communication/identification far outweigh the benifit of getting closer to having full town powers, especially since our guesses are so limited on day 1.
Now considering that mafia would be thirsty for information right off the bat I tried to prevent the flow of hints/theme clues to everyone as much as possible, while watching for people baiting conversation about the theme. Right off the Bat Soup/Raz comes to mind. Then I wanted to see if I could tell who desperately wanted the theme to be revealed, so I announced knowing the theme knowing that this would gather a lot of mafia attention while having low odds of even having a doc to protect me (OS/Raz comes to mind). Conversely if I was mafia I would have never made this play, I would have simply laid back and waited for opportunities to drop hints.
The reason why I vote OS over Raz is because I believe he really understand all of this, but sees an opportunity to still push for theme while somewhat identifying his possible teamates. Other people I can't tell if they didn't realize how handicapped mafia is atm.
TLDR: Pretty much don't discuss the theme until day 2.
