The best versions of these games are set up to provide more contextual information than just "Player B Died Last Night". Classic Werewolf or Mafia, all information is public information, outside of people just talking to each other in whispers. Among Us adds a map and location information - you have to have been near the person who died to kill them, so if someone died in one room, you suspect players who were near that room or can't account for their location. Clocktower or One Night generally add information that only one player gets, such as being able to know if they're seated next to a bad player, which is powerful, but easy to lie about and risky to just admit since it makes you a target for the bad people.
