Are there any games which incorporate a legacy aspect to their Social Deduction?
With repeat players there is often a social legacy: “Watch out for Bob, he’s good at guessing the Werewolf” or “Alice always misdirects when she’s the traitor”.
I wonder if having players who survived / won previous rounds bring a powerup or unique special ability into future rounds would be compelling. My hunch is that by having higher stakes of difficult-to-earn, easy-to-lose power(up)s, surviving or losing a game would feel more intense as would the betrayals.
Perhaps there’s something where a player building power as a surviving town member can exploit their power as the bad team, but doing so might make it too obvious that they have a bad team identity.
