Mafia - Star Trek Version
Some of the roles are obvious, duh. I thought it would be an interesting twist to combine a couple of the roles as well. And this isn’t completely thought out. I don’t really have any interest in moderating a game, so if someone else wants to run a version of this, just give me a little credit for coming up with it. 
Roles:
Captain Kirk - (what you thought this was gonna be TNG? Nope!) - Vigilante/Guardian Angel. Kills each night in search of the Alien Life Form. Can also use his Kirkiness to protect one person on one night only. There is only one Kirk.
Dr. McCoy - The doctor. Uses his powers of healing to keep one person safe from the Klingons or Alien Life Form each night. There is only one Dr. McCoy.
Spock - The detective. Always right on his investigations because of is unparalleled powers of logic. Except if he investigates Khan, who will show up as a Red Shirt Crew Member. There is only one Spock.
Lt. Uhura - Mason/Informant - has access to the Klingon boards and knows the language, but does not post to them. Klingons know there is someone monitoring their transmissions, but does not know who. Knows other masons, but not if they have special powers. There is only one Lt. Uhura.
Sulu - Mason/Cop - Investigates one person each night. A crew member will always show up as a crew member, but other roles are 50/50 and can show as any other role if wrong. Knows other masons, but not if they have special powers. There can be up to two Sulus.
Scottie - a plain mason. Masons know each other, but don’t know if the others have any special powers. There can be up to 3 Scotties.
Red Shirt Crew Member - a plain vanilla townie who knows nothing and will likely die if picked for an away mission.
(There are no Away Missions, but if you wanna call the lynchings that, I think that would be cool.) Everybody in the game who is not somebody else is a crew member.
Khan - Leader of the Klingons. Will show as a crew member if correctly investigated. There is only one Khan.
Klingon - the bad guys. Depends on how many there are in the game as to the exact number of Klingons.
Alien Life Form - Poses as a crew member and kills every night. Wins the game if it is still alive when either the crew erradicate the Klingon menace or the Klingons take the majority. There is one ALF.
Game play is much the same as the other games.
What do you guys think. I wanna play this one!
