Very well played, right from the beginning, kira. You managed to get in with toothache early, and persuade people the entire game you were with the students. In the end, as things winded down, it was clear there were going to be one of two results: 1) you kill off the remaining death eaters (being a student), by wiping out everyone on your suspected lists (which, in the end, had they been true, you would have had a 0% chance of failure, hitting at least one person before the DEs could knock the students down to two), or... 2) what happened. As you kept hitting students it seemed to be getting more and more likely that you were a DE, along with several "over-dramatics," most notably with the bg that you insisted needed to protect the right person when you were so "sure" that the four people you had on your list were clean, which had they been you would've been in a winning position regardless if you were a student. There's also the fact that (iirc) you only hit ministry and students while you were directing the kills (and if you did hit a DE, I'm pretty sure it was only one), and after a point, you stopped taking the initiative, instead letting someone else in the game pick a name from your list of "death eaters," then going along with it. If you want to know the truth, on the last lynch, if I was still alive, I would have lynched you.
The PM I sent you (no mekkah, it did not and could not have influenced the game), was congratulating you on winning, basically, regardless of what camp you belonged to, before the game actually ended. I actually was already questioning you being a student at that point, but everyone else clearly believed you. So basically, it really didn't matter what happened at that point, as not only had you secured the people's trust, but you had also successfully implemented a backdoor for when you continued to hit students in your lynchings, to use as a way out when people actually realized what you were. It was quite genius, actually.
Although... there's still something I'm curious of... what was your "test" that you prepared, kira?
Anyway, it was a fun game, even after I died, and had to just follow along with the thread without posting. I'm looking forward to hopefully playing mafia again with you guys sometime in the future.
