Mafia 90. The Tale of Oldforest.

I think that's right. In the previous Mafia game, after our and the Hero's death, we were practically the authors of almost all of Hekasan's posts. ^_^
As a result, only a few people actively participate, and the rest do what they are told, which is also not good. Plus, there is a need to eliminate the most cunning and dangerous ones so that they don't blab something they shouldn't. And more tactical diversity means more interest. The main thing is not to overdo it.

Well, Snowman has already explained what this entails. It turns out that experienced players, in case of their death, start controlling inexperienced players, preventing them from gaining their own experience and playing their own game. But if this doesn't convince anyone, then okay, I can cancel this point.

This is especially true if the killed Mafia member is an active player; their presence in the chat is crucial for the Mafia's victory. Yes, they will give hints about what to write and what to do. But this is not a one-player game. If, for example, there is a foreman and several workers on a construction site, and he gives them instructions, it does not mean that the workers are not doing anything. The foreman has his job, and the builders have theirs. The same is true here. An active player who, on his own initiative, remains in the chat after death simply performs a certain special role. The other players still remain necessary; without them, it simply won't work. Well, I'm just being a captain now, but you get the idea. However, an active player who encourages them, gives advice, and can send an investigation if the others are not available (which is important!) is essentially the only thing that can balance the situation in a difficult situation.
Of course, if all the players are active in the chat, then you can ignore this. The others will cope. But practice shows that this is not always the case.
