Thanks for the question, it's a very interesting one! I have to admit that I have no idea how to write a game rule to prevent someone from intentionally losing.Even if all negotiation and transfers were banned, a player could still chose actions to hurt his or her own position and purposely help another player until that other player has won.
So, for my curiosity and for those who might face this problem, let me ask: What house rule would you use to prevent such an occurrence?
Best regards, and I hope that you like how the game plays! Volko
