I'll copy here. Cut and paste follows...
Ever play Credo, the card game from Chaosium where you play out the Council of Nicea and determine the future path of Christian orthodoxy, assembling a creed in the process?
That's small potatoes compared to The Last Supper, an entry in the Iron Game Chef 2005 competition.
The Last Supper must be played in a single session and incorporates a potluck supper. Each participant should bring one or more dishes, and they are encouraged to coordinate for a satisfying meal. The GM will provide the beverage.
One participant - the GM - takes the role of Christ. The remaining participants - the players - each play one of the twelve Apostles. Of these Apostles, some - the evangelists - will go on to write the Bible. Others - the proselytes - will travel unto the corners of the world and spread Christianity to the masses. And one - the traitor - will betray Christ to the Romans and initiate the crucifixion. Without a traitor, all other efforts will fail.
The story of the “real” Last Supper should be considered simply one example of how the game might turn out, just as our world should be considered an example of how the world might be shaped by Christianity over the millennia which follow this event. There is no guarantee that Judas Iscariot will be the traitor, nor that any other disciple will follow the destiny we see for him in our world. Ultimately, the point of the game is to interpolate the doctrine of the church which will form around Christ, and to simultaneously extrapolate the effects of this doctrine on the world to come.Credo was really cool. Sounds like this would be too.
("Sputtin," [I'm not sure if the spelling is correct], is an admonitory word older Reformed people of Dutch extraction in West Michigan sometimes use to describe speech that threatens to go over the line, or actually falls over the line, into blasphemy. "Hey, that's sputtin'.")
UPDATE: Hours after I write this I happen to see a post on the author's blog, describing a playtest of the game -- and noting that the final rankings for the game chef contest are out -- and the Last Supper was one of the two runners up! Neat.
There are far more cool ideas and designs on the Iron Game Chef entry list than made it into even the finalists. To enter that contest, and make a serious effort, is in a real sense to win.
