Ok so it starts off with 20 peeps, they all do a competetion and the winner votes for someone to SAFE and then that person chooses someone to save, and so on and so on until there is only two people left, those two either have to play a new game and the one that loses is elimanated or the one with the lowest score from the game that everyone played is eliminated.
This way the players should be careful who they tell there score to, and instead of it being a numbers game like all the other games on tengaged, it would be a competetion game. Also, The winner of a Duel will get either +1 Karma or +1$T or something
