According to this BoardGameGeek post, it is never advantageous for a “good” character to pretend to be part of the “bad” team in a social deduction game.
every. single. time. you explain these kinds of games, you need to hammer the point home that it makes absolutely no sense to pretend you're a spy/fasist/werewolf/whatever when you're in fact a villager/good guy/liberal.
Talking specifically about The Resistance and The Resistance: Avalon (since they are more or less the same game), the "hidden" Loyalists are expected to pretend to be Resistance members and the "hidden" Evil characters are expected to pretend to be Good characters, respectively.
Is it ever advantageous to pretend to be on the a Resistance member and pretending to be a Loyalist, or being a Good person and pretending to be Evil? Or is this person correct: it is never worthwhile?
