Well, I played and won my first large game yesterday, but not how I wanted to. I wiped out every minor civ, built up a major assault force, and wiped out every civ, except for one. I had an alliance with the Yor, and they didn't have an alliance with anyone else, and I couldn't break my alliance with them, and therefore, could not destroy them. I tried placing as many influence starbases around them as possible, trade them stuff to buy off their planets, everything, and it didn't work! How do I break alliances so that I can destroy them all?
