I've been thinking about how you could add the enlightenment win condition to the standard game..
Heres my idea! What do you think?
Every round each player can declare a military and a political conflict each, for a total of 4 conflicts per round. This means that there are 4 rings that can be claimed in a single round.
ENLIGHTENMENT RULE
If a player claims all of the 4 rings in a single round from all 4 conflicts, then they have the option of declaring a bonus fifth conflict (military or political, their choice).
If they win this conflict and claim the 5th ring, then they win the game through enlightenment, by claiming all 5 rings in a single round!
