"By building alliances and friendships with other factions and empires, you become highly valuable as a friend and simply too dangerous as an enemy. When you have accumulated enough Diplomatic Victory points in the great game of galactic diplomacy, you become the dominant political force in the galaxy."
So, how do I accumulate Diplomatic Victory points? Does any kind of trade count? Like, even if I just give someone a flat 1 dust in exchange for nothing? Are different deals worth more than others (alliance seemed to be worth a lot)? If I have peace, open borders, & cooperation agreements with everyone and everyone likes me, what else can/should I do to accrue points?
