It's fun to see how much the rules have changed from the first mafia game, where there were practically no rules, to the current one. I must say the best addition, in my opinion, is the no outside-talking one.

These two are pretty sweet too:
* Minimum 5 posts every 2 days. So you have to have made 5 posts in the thread between the current day and the previous day. Failure in this will result in death by town lynching(doesn't count as the day lynch...just an extra lynch)
* There are no replacement players.
