Mafia, from what I understand, is a very popular party game adapted into a forum game that is also incredibly popular. The general idea is that a certain number of players are evil and want to kill those individuals who are not evil in a night phase. Those who are not evil have the opportunity to 'hang' an individual at the end of the day phase by voting for that persons death.
If enough people are willing to give it a shot I think we may find this game quite entertaining. What do you think?
