Oh but there are
rules, I could have been a lot stricter as some forums who specialise in Mafia games have a whole array of do's and don't including revealing off-thread PMing and penalties for broadcasting them even if you're out of the game.
For instance the 'Gawping' participation condition is, so far as I know, a unique or very rare concession as generally non-players can't join in at all even off the main thread - but it fits A-M perfectly of course.
That's before we even get to the various cop and killer roles you can factor in, except they're for high participation games which get a lot more vicious and unbiased.
This one was about as simple as I could get it as most people here were new to it and we've all had great fun and made it pretty complex and entertaining, which is the object after all - so well played everybody and here's hoping we get some more participants next time although I think keeping the Gawping in as an option does add to the general craziness and give 'environmental enrichment' for those who like throwing spanners into the works but can't spend too much time participating (or are too shy to get their toes wet!)
