You think things through. I like that. in Order.
-If player C finished 3rd with 6, making it a tie with him and player B, then It will be decided by who had the best gameplay. Ex: if Player B got to 6 centers with little to no effort, say he is France and gets Spain and Port and Belgium due to a German support, and then he just helps Germany coast into an easy win, while Player C fights for the whole game to try to win it, he will go over B. it will be discussed more if that situation arises, and it will be open for discussion by all participants.
-If there is a 4 way draw with 3 players having 6 centers, then it will follow similar proceedings as the first point made.
-For this tournament, Draw> Survive. so if you are in a draw with 6 centers, you still go over a survive with 6+, because you were able to help stop a solo, which obviously means you played a better game.
