Well lets see if I can help get some conversation going. I don't have a lot to work on right now and I am going to talk about the IC posts here. However it can tricky to see what is game-related and what is story/character related so I wouldn't place a lot of weight on what I am about to say here.
The first player to post was Animus but I am going to assume that it was all story related as he claimed to post it before he got his role.
Next would be Asuna's post. I am not going to lie but this one did make me raise an eyebrow. Her post sounds as innocent as possible. If I was a killer mafia I would want my character to look innocent in the IC as well. However it is hard to say weather that is her game plan or if she just planned her character that way.
In Contrast we have Mikes post. It might be just me, but I feel like his character looks a little suspicious. I don't think a killer would knowingly make there character look suspicions. However is still entirely possible that he planned this personality before he got his role.
Lastly we have Night's post. I am honestly having trouble seeing even a little bit one way or another.
I know I am picking on little things right now but that is all I really have to work on. But hopefully this will help get some other conversation started so please tell me what you think. Is my analysis all wrong? Am I over analyzing? Is there something I missed? Can we dance if we want to, can we leave your friends behind?
