Before I dig into Nautilus' list and the other posts, I think I should expand upon my wild suggestion of a benevolent mafia, given its traction. I know it's a bit of a stretch, and were I roleplaying I'd consider this in the realm of out-of-character, but the reason I proposed the idea largely stems from our own game master, Kiyoko. I'm only loosely acquainted with her through another board (and her lovely art <33), but from reading parts of the previous game and observing how she has structured this one, it's easy to see her character: she wishes to foster growth and encourage newcomers. As she more-or-less invited and is thus familiar with most of us, it stands to reason that she would attach herself to individuals of similar character--especially those from the previous boards that she has perhaps known for years. So, this caused me to wonder if the mafia were of similar experience and mind as Kiyoko and thus wished to raise newcomers from infancy before leading them to the slaughter. I'm not sure if this line of reasoning is inappropriate or not given that it uses out-of-game information, but, then again, we keep referring back to the previous game... which raises another point!
So, as of now we've heard from most posters. With the exception of Mr. Alice and now possibly Sammiya, everyone that's posted has highlighted the link between Drandahl and last game's mafia. There was also a comment as to who followed the previous game. Our player list is Alcasync, Nautilus, Rasei, Sammiya, Megrid, Mr. Alice, and myself, not counting the deceased. Of those, Alcasync, Megrid, and Mr. Alice all played in the previous game, and Sammiya moderated it. Nautilus has previously stated that they read it, and I know for myself that I read a good portion of it. I would assume Megrid followed some of it, or at least checked the thread when it concluded. The only wild card here would be Rasei, but I imagine curiosity over the first game ever would lead to investigation. So now it's more a matter of if we let that influence speculation, but it does seem to have been the first thought among most of the players.
Now replying to others (sorry, I can be a bit of a rambler? x-x).
For Alcasync, there are probably too few veterans, it's true, though there's the possibility of a mixed mafia where the experienced one suggested Drandahl, thus leaving town as having two veterans and three non-veterans. If it was a charade, that'd cause the majority veterans (aka town veterans) to turn on the non-veterans, which would be more even in numbers. We also still aren't completely sure about Rasei. In this case, we might be dealing with a mixed mafia and veteran majority for town. I'm not committed to this idea, but more exploring it. It kind of hinges on Rasei's eventual response.
I am curious, though, as it'd help me to further my own reads. Earlier today you said that you didn't expect Drandahl to be the first victim. Which player or players did you expect? Since you suggested mafia would target stronger players first, with perhaps the exception of Megrid given their limited playtime in the last game, were you thinking it'd be yourself or Sammiya? Although, Sammiya hasn't truly played yet, either, so they might get the same treatment as Megrid (I swear I'm not trying to push this altrustic mafia agenda!).
For Nautilus, I agree that it makes sense for the mafia to operate efficiently. In a vacuum with no saves and no lynches, we have two more day cycles after this one before mafia wins. In practice, with a fewer number of players it'd increase the likelihood of us bringing the mafia down to 1 player or getting a save off, but the point still stands.
As far as your theories go, I addressed the first above by stating it's certain all of us (except maybe Rasei) are familiar with the previous game. Granted, that doesn't necessarily mean we're well-versed in Drandahl's playing style. I think your second theory is very likely, if not probable. It's actually a relatively elegant and simple answer to why Drandahl would be targetted... beyond being randomized, as is your third point!
Okay, sorry, I'm long-winded. I look forward to seeing Rasei's post and a longer one from Sammiya!
