It would be nice to be able to select the amount of ends in a full game. Like 2 ends, 4, 6, 8, 10 ends or as many as you want, like now. In this system for 2, 4, 6, 8 or 10 ends your ranking would not be changed until the completion of the amount of ends that both players agreed on. This way just like real curling, if you decide to leave a game because of a bad end, you lose(your ranking goes down, winners goes up)... just like shaking before the last end is played. It would add a new dynamic to the game, make it more like real curling. The way the game is now, people don't play to win the game, the just play to win an end... If they miss a shot they leave, and if they make a shot for a big end they leave, so they don't have to give up hammer and lose the points they gained... Allowing people to set the number of ends and not changing the rankings until completion(negative rating if game is left before completion) i think would really add to this wonderful game.
