Westphalia concerns the diplomatic negotiations and military campaigns that brought an end to the Thirty Years War and Eighty Years War. The question isn't a matter of who "wins" the war - that was decided a long time ago. Instead, each player seeks to arrive at a settlement that meets their own political, confessional, and economic goals. These goals are not mutually exclusive: if multiple players meet their victory conditions, they all win. The trick is, if all six players manage to meet their goals, then the game goes to a scoring round, and only one player wins.
