There are a couple things that sounds similar to:
Those weekend-long LARPs in which you pretend to be a fictional person in a fictional setting for a few days. Depending on your role, you'll have places to be at certain times, events to participate in, perhaps even some work to do if it's appropriate to the character. These don't usually tend to have a mystery attached, though they certainly can. If so, it'll be handled similarly to below:
Murder Mystery Games(not necessarily a murder, though that seems to be by far the most common type of mystery); usually only for an evening, though they can and have been made for longer durations. You're given a character to play. It'll list personality traits and other relevant info, give you certain pieces of information you're expected to let drop in conversation at certain times, perhaps even give you some tasks to do.
I figure it wouldn't be too difficult to change up a few things to make it more like the games you mentioned. Perhaps the clues and activities are meant to give hints about who the "wolves" or whatever are(and I assume each guest would have 1 or 2 clues they could actually use to misdirect people; can't leave them totally merciless after all), and each round of play's new death is the result of a vote. Honestly, this is sounding a lot like a LARP for Among Us(only with a fancy dinner party or something because heck if I'm going to one of these things and not getting fed), and tbh . . . I'm kinda down for that. Reskin to wolves or vampires or mafia members or whatever as needed.
