One of my favorite designs, which never got played here, was the Departed. I wonder if you can get it started over there. If so, just give me credit. I may arrive to play.
Were Departed
There is one vote, and it is to lynch.
There are three teams: the Cops, the Irish Mob, and the Innocents.
The Cops win if the Irish Mob is eliminated.
The Irish Mob wins if the Cops are eliminated.
Each Innocent may choose his own win condition at any point in the game: he may choose to win if the Cops win, or if the Irish Mob wins. Once he has chosen, the Innocent may not change his win condition. If the game ends on the day that the Innocent made his choice (ie, if he waited until the last moment to choose), he loses.
Turf
There are five territories in Boston. During the night, the Cops and the Mafia can claim a territory. If they choose the same territory, the territory becomes "Contested" for the turn and neither side can use the ability. Otherwise, that territory falls under their control during the night, and they gain the power that comes with that territory for that day.
All territories except for Southie and Downtown start "Unclaimed."
Southie - The Irish center of Boston and the Mob's stronghold. Begins as the Irish Mob's. Can't be claimed by the Cops unless the Cops control three Turfs. The controlling group may Seer one person a night.
North End - A predominantly Italian neighborhood. The controlling group may secretly protect one person from night kills.
Kenmore - Home of Fenway Park. At night, the controlling group's kills go first, after lynching. This is significant because it may interrupt the target's ability (such as the Captain/Mob Boss or Vigilante). Furthermore, near endgame, if there is one Cop and one Mobster left, and they each choose to kill the other, the group controlling Kenmore will win. If nobody controls Kenmore, kills are considered simultaneous (so, in the hypothetical shootout, both teams lose).
Back Bay - An extremely wealthy neighborhood. The controlling group may secretly protect one person from lynching (a successful lynch vote against that person will fail to kill him).
Downtown - Home of the Government Center and financial district. Begins as the Cops'. Can't be claimed by the Irish Mob unless the Irish Mob controls three Turfs. The controlling group may Seer one person a night.
Cop Roles
Captain - This person may claim one extra territory in Boston for the Cops. Can also claim with his group, doubling the power of a claim (a claim made by a single Irish Mob entity will be overridden). Counts as a Cop.
Cop - The Cops arrest (effectively kill) one person at night.
Rat - This player publicly appears to be in the Irish Mob. If Seen by the Mob (ie. via Southie ability), appears to be a normal Mobster. This person is actually in the Irish Mob, but has one contact (chosen randomly) within the Cops. Wins if the Cops win. Doesn't count as a Cop for victory conditions. (Because of the existence of the Leak, it is highly inadvisable for the Rat's contact to reveal the Rat's identity to the Cops.)
Irish Mob Roles
Mob Boss - This person may claim one extra territory in Boston for the Mob. Can also claim with his group, doubling the power of a claim (a claim made by a single Cop entity will be overridden). Counts as a Mobster.
Mobster - The Mob kills one person at night.
Leak - This player publicly appears to be on the Cop team. If Seen by the Cops (ie. via Downtown ability), appears to be a normal Cop. This person is actually in the Cops, but has one contact (chosen randomly) within the Irish Mob. Wins if the Irish Mob wins. Doesn't count as a Mobster for victory conditions. (Because of the existence of the Rat, it is highly inadvisable for the Leak's contact to reveal the Leak's identity to the Mob.)
Innocent Roles
Vigilante - The Vigilante can kill one person a night, but only after he has chosen his personal victory condition.
Seer - This Seer is the only person capable of identifying a Leak or a Rat.
