My impressions from the first day are as follows:
Arandor – Romeo's move in the first night speaks in his favor, but that's just probability. In terms of gameplay, he's not rushing to take advantage of the slightly increased trust he has from the town (and he should).
Neira – I would say she's about the same as Kosh. She tries to engage in general discussions, but she's good at both.
Master – so, it's likely that both of them are not Mafia. First, in terms of roles, this is only possible if Master is Goriot, and Medzh is Grandet, but besides that, they are also attacking each other too persistently. Something to think about: is Master Mafia, who copied Medzh's role? This scenario looks interesting, attacking a Mafia member about whom he knows everything, that's a great strategy. However, the probability is at the level of "guess for yourself." In terms of gameplay, I don't see anything like that.
Cop – that's me.
Nebok – I just want to confirm that yes, he's Town, and I almost agree, but I won't rule out the possibility of him being Mafia. Nebok-Mafia is cunning and ruthless, and almost always wins, we know that.
In conclusion! Medzh + Yashur/Neira/Arandor, pick 2. These are the Mafia.
As for the Mafia... Well, there are problems with this player, logic doesn't work well here. There's a chance to figure it out if he really stole Balzac's role and used it to kill today, but that's weak. It would be good to know who the Mafia is, but it might be dangerous to eliminate someone now, without a clear understanding of the Mafia roles. Also, I like the idea of Master being Mafia, but I like to look for patterns where there aren't any...
