When I was a kid i had a game of Clue that I lost the cards to for a while, so I redid that rules so that basically, each piece started off with a weapon, and you moved around the game board trying to kill the other people before they killed you, and different weapons were more or less useful (revolver > rope) and once you killed someone you got their weapon too, and last peice standing won.

I find it funny that my bored only child reworked version of Clue was more true to the idea of that kind of dystopian setting than Hunger games the social media game is :P
