The premise is simple. The players, as new posters on a highly active forum must troll, cajole, flame, joke, and debate the best they can on a thread started by the GM, who will check it out again in 8 hours and judge the posts up until that point.
Each player is essentially an actor, because as a poster they will be posting with a personality not of their own, but acting genuine. A quality may be "racist", "religious conservative", or "hot 19 year old" but the idea is to post in the most outrageous entertaining way that you can without being accused of being disgenuine by normal posters on that forum.
Teamwork is essential and will be rewarded by the GM. Both purposeful teamwork with each other (playing off of each other's ridiculous posts) and unwanted teamwork with normal posters' posts (playing off of other people's posts rather than just ignoring them).
There are several laws to the game. If a player breaks a law they are disqualified from the game (and any points the GM awarded their posts won't be in the running for winner of the game). The laws are:
-do not be accused of faking your personality (ie: the bad actor law)
-do not get banned (ie: the take it to the edge no further law)
-do not be accused of having a previous relationship with the other players (ie: the secret conspiracy law)
Follow these laws and your posts will be judged for their teamwork, in character-ness, and entertainment value by the GM, on a scale of 1-10. The player with the best score after the GM announces it to them gets to pick the next game the group plays, hopefully a real RPG and not silly party game crap like "For the Win!".
Setup: The gameplay takes place within an 8 hour period of the GM posting a thread of a random topic on a forum. However it is suggested that the GM and the other posters join that forum two weeks in advance so their chicanery is not as suspected. It's also not suggsted that the GM announce the disqualifications and scores on the thread at the end of the game, unless they all don't mind getting banned.
Oh, and if it wasn't obvious, it's the GM that assigns each player with a characteristic or character (souther racist, retarded midget, ect.) to portray in their posts.
In theory it's an idea that has massive entertainment potential, but in actuality its something no one will ever want to play (well, they'll want to play it but better judgement will take over).
It takes the time period of 8 hours in no matter how many sessions, and the package 2 qualities of law, actor, and team.
