A new mechanic for sandbox mode!!!!

[ElTobaQC 10]

You could add an option to be the one who decides the negotiations, for example, there are several wars in a game and in the wars a winner comes out instead of the one who decides being the winning country, it is the player who controls the game. It would seem like an interesting mechanic because I sincerely want to control a game that way, I hope that if you add it it would be an original mechanic.
