Let's try this. 9 players. Among them, I, for the sake of balance, will personally choose one maniac from those who can, at least to some extent, deceive others.
All the rest are absolutely ordinary peaceful players, without any special features or neutral roles.
The roles will be revealed during the first two days. At night, there is no point in hiding or revealing them, because there will only be one murder, and the roles are the same.
