agentcarr16: Imagine if I had claimed Robert of the Red Cloak, and then the OP messaged me and said "actually, the Red Cloaks are what I'm calling mafia this game. Guess I forgot to tell you that, sorry."
You're completely missing my point. In your example, the PM would have been something like this:
Hello agentcarr, you are Robert, Red Cloak regular.
Powers: In the action phase, you make discuss your plans here: [REDACTED]
In the action phase you can target one player to eliminate from the game. Only one of the Red Cloak can perform this action each night.
Win condition: You win when the number of Red Cloak members is equal to or greater than the number of townies.
The whole damn PM makes it obvious you're a mafia member, the win condition, the fact you can eliminate people at night. The scum chat!
To start claiming at the beginning of the game would be silly if you were town, but to do so as mafia is 10 times worse. It doesn't matter what the mod is calling the mafia in this particular game, it should still be obvious to you that you
are mafia and thus ridiculous to start claiming your actual identity.
It's really only not your fault if your PM had the wrong win condition.
