It sounds like you have the same Idea as me...
EDIT: I'd like to propose my Idea. Is it possible that there are no mafia? There are a few pieces of evidence I'd like to bring to light when considering this.
1) opal has said that this is a "slightly atypical game of mafia" and that we "shouldn't necessarily take anything for granted". This could mean a number of things, one of which being that there are no mafia. Do note that nowhere in the main post did he say that there would be mafia.
2) He also asked that no one who played this version of the game before join in this round "because it's no fun if one person knows what's going on". Someone who played this version before would be aware of what happened so... yeah...
3) To quote him, "In some ways this is an experiment which might go terribly wrong, but I think it will be an entertaining game."
4) Leafpool's death could've resulted from a Healer clash or a Vigilante.
So, um, I think he's playing with our minds here. If you think I'm crazy and stuff then okay, but that's just my theory.
That is a possibility... Okay, that's better than my idea. Especially now that we've another death. that. sure doesn't sound like a healer clash. But... wouldn't a vigilante be the same as a sole mafia, in that case?
Hm. I have an idea and a proposition. I don't think anyone would willingly, truthfully, give out their role - either it's helpful, in which case you'd be prime mafia pickings; or it's harmful, in which case yeah. However... this is a thirteen-player game with an expected twelve players. Could one of us be a non-roled citizen? I know it's rather unlikely, but...
Agh. Okay. This is too much dancing around. What I'm trying to say is, this relates to yesterday's talk of aliens and the number thereof. My previous idea was that... /everyone/ got assigned an alien role. (Except for perhaps one or two mafia, but it /could/ just be /opal/, in fact, killing Leafpool and Zora...) I mean, the idea that there may be more than one alien was certainly on everyone's lips, and I've been in many mafia games, but none of them have had more than one, no matter how large the game got. This is a relatively small game, so what if people were thinking about it because they too were aliens?
And okay yes, I realize this puts me at a huge disadvantage if I'm wrong by basically declaring my role as alien. But don't vote for me - I was activated first night. Yup. (So oh well, if all this is just my fantasy and everyone proceeds to go "er no I'm not alien, wtf are you talking about", the mafia or whoever'll kill me to get me out of the way. I don't like alien role too much anyway, it's way too hard to win. And I can't even be on as much as I'd like anyway! So it's all a win.)
So what I'm asking all of you is: do you have the alien role as well? Or do you have a different role? No specifics needed, but I'd really appreciate if the truth was told.
(Note that if all of the above is true, I don't have any master plan besides being all like "awesome I figured it out!! ... now what." \o/)
