I've often pondered how to insert myself into my own games fairly, however it is totally unfair on the other players if I could vote or kill. I know too much.

The best that I could come up with was Golden Rule (I only win if everyone kills each other) and Psycho (I could only kill as the other half of the personality of Omanes Alexandrapolites, and only whoever he decided to investigate).

It's fun, but I cannot actually affect the outcome of the game, and I don't get to actually decide to do anything, and given my reputation, I can't have every mafia game I host have a wasted turn lynching me when I am not a target for a lynch.

Trust me, I'm sure you would have noticed Toyoda Guzman walking among you by now. He looks like this.
