Ok...we weren't great at writing the rules. Basically...as a cop you PM the game master and tell them who you want to protect that day. Zombies PM and tell them who they want to attack and supply rock, paper, scissors. If you are attacked the Game Master will PM you to choose a single Rock, Paper, Scissors. The results will be PMed to you. Killers will PM and write who they want to kill. That person is automatically killed the next day and will be reported in the story.
The Story will focus on survivors and Zombie kills and such. So the story will tell if a Zombie was killed, a human murdered or what not...and will list the number of Zombies now present in the game, and list the number of survivors and special people.
Daily community. Each day there is a coin toss to earn money...it occurs at the end of the day, so people can post their coin predictions and wagers each day. Trading of weapons, and money can occur daily to. In PMs or not. Even Cop and Killer Roles can be traded in this manner...you must inform the game master and both people must give consent before that happens...but it is doable.
The game actually doesn't take much time at all...in fact it should be less time consuming than Mafia.
