Add a new Rule to the Ruleset.  Call it “Political Victory” and give it the following text:

If all Players not on a certain Team are on Teams Friendly towards that Team, the player on that Team with the highest Score achieves victory.  If two players would simultaneously achieve victory under this rule and neither of them is the Leader, only the one with the higher score achieves victory.

If a Player wins by this Rule, they are encouraged to show favoritism towards their teammates (or those who were their teammates at the end of the dynasty) during the first two weeks of the next dynasty.

If a majority of EVCs on this proposal contain the text “No Favorites”, omit the last sentence of the new Rule.
If a majority of EVCs on this proposals also contain the text “colorless”, the Rule this proposal creates does not become a team rule.
