I guess I can submit a loose loose outline.
First, before I started the game, I came up with the "Terrible horrible Ravio company" idea. I sent out a few PMs as Ravio once we had our accounts, but before we had our roles. I think I recall sending one to Fi, at least.
Once I got my role, I wanted to play as the "Useful idiot" for anyone who could kill me via night action. That was definitely my number one goal. I didn't want to die until the end of the game. I also knew to get there, I'd need some help. Or at least a person or two less who'd want to kill me. The only way to do that? Be useful.
I told my role to Hestu via my regular "thatguy" account. Didn't ask anything in return. I figured if Hestu was a townie, at least they wouldn't try to vote me off. Killer, Majora's Mask, or Mafia, also would avoid killing me. I just knew I needed someone even slightly on my side. Turned out to be the best move of the game, without a doubt. I avoided being killed by the mafia. The mafia avoided being blown up. Hestu eventually told me their role, and we coordinated our votes to save us via the "Votes for sale" manuever. (Remember, useful idiot. If the mafia or killer finds I'm for sale? I can be bought and am less of a threat.)
Funny thing, at that point, while I'd been goofing off with Cucco, we hadn't hardly discussed the actual game at all. I guess I fed him ideas for fun graphics and the Ravizon website, which is outstanding, apdude. Incredible!
He decided to buy the information on who bought the vote to save themselves the day before, Hestu. And that night, Hestu died. I'd found my killer. The next day, I sent Cucco a message that was innocuous enough, but heavily implied he was the killer, and he confessed.
I was able to figure out Great Deku Tree from a few things. Fi's reasoning to vote out Hestu was a gigantic logic leap. No one would make that move unless they knew who Hestu was. Great Deku Tree followed suit quickly, IIRC. It seemed the ploy was to vote out a mafia member, and then claim to be some sort of townie heroes. When neither me nor Hestu died, I figured I could get in good with the townies by telling Agitha/BeautifulShy she'd been duped. It worked well enough. I guessed the Deku tree was the last mafia member, and lucked out that my read was right.
I felt like at this point, I was sort of a de facto godfather. We had our triad. You (Cucco), Me (Ravio), and Deku Tree. Perfect for a You, Me, and Dupree reference. I didn't even see that movie.
Anyway, I kept up with the dumb distractions, kept absorbing attention and votes nearly all game, and it played to my favor. Anyone facing persecution would appear to be second in line behind me, and every day I managed to convince just enough people to keep me alive. Didn't wind up hit, didn't wind up dead. Was useful to the mafia, was useful to the killer.
What should have happened, what would have cost me the game? Deku Tree or Cucco outing me as the bomber. All they have to do is make that out as soon as they knew, I'd be voted out. It would be over. No one would be happy about it, but a few townies would have snackrificed themselves, I'm sure. Then it would be a fair game.
I coordinated hits between the Tree, who didn't know who the killer was, and Cucco, all to lessen the number of players as long as possible.
I suspected both Dampé and Cia to be Majora's Mask due to their aim to create a tie, delaying the game. I suspected Cia most. For some reason, no one really wanted to hit her, which was fine. Her being in the game meant more people were distracted from hunting the bomber, right up until it was too late.
Once we got to yesterday, I wouldn't be able to survive a vote-out, but the tree and the killer had too much vested. They weren't going to sacrifice to get themselves the win. It would be the townies who were the threat. First, I tried aiming at Cia, who, I thought we all knew was Majora's Mask. She voted for Agitha, and I figured "Okay, a chance to kill the townie leader. Sure." Agitha was quick, though, and after some discussion with me where I framed Tingle as the bomb, we decided to be heroic, and get other players on our side, even. I knew at this point my cover would be gone, but tomorrow we'd have five players, one who is inactive, and so I thought my chance of losing the vote would still be somewhat low.
The funny thing about all of this? Had I been Majora's Mask, I would have likely made it to Day 8, as well, with finding the fairy. I had guessed 13/18 and knew all the prizes. Hooray! Also funny, if you had given my role to Agitha, she made it just as far as I did, and if she played the way she played the whole game, would have won as well. Just goes to show a lot of possibilities are out there. It was a fun game, and I'm glad everyone or almost everyone participated.
