This game (under the "Mafia" name) has been popular in Finnish math-contest circles since some time in the 1990s, probably as a Russian import. In large groups there can be many more roles, such as the axe-wielding lone killer, the police chief who gets reliable information from the game master, and the doctor who can rescue a victim if they guess correctly. Lots of fun.
Someone mentioned Blood on the Clocktower <https://bloodontheclocktower.com/> which has many more roles and a more complicated game that can take hours. The upside is that you aren't out of the game when you are eliminated.
I also learned about Mafia from participating in math competitions (in the US)! My teachers were Turkish immigrants and they introduced us to the game and we had a blast. it did suck for the person who died on night 1, though.

In the other direction, there is a One Night Ultimate Werewolf ruleset <https://www.wargamer.com/one-night-ultimate-werewolf/review> that leads to a much faster game because it's not iterated.
