I suppose I've played the game with different motivation, to be specific because it's hilarious when someone completely messes up.
The funniest game I had, a few weeks ago during a social for my last show. One of the Mafia was a girl called Natalie, who was a terrible liar, and was accused during the very first day. In her defence she said "It was me, I killed the bastard". However, as she was so funny to play with we kept her in and killed the Director instead.
It later got to the point where she was the only member of the Mafia left, tried to commit suicide, but was saved by the Doctor and survived another few rounds.
You just don't get that sort of game on the internet.
