Even though I am told that alliances suck, I would like to attempt an alliance victory.
Even when I have the "Alliances" technology researched, my Treaties section of a trade screen has no Alliance option, only Make Peace and Attack. This is true even of my most friendly alien neighbors.
What do I need to do to get the Alliance option as a treaty I can offer?
Am I being dumb? Are alliances made in some other way? Do I need more technology or better relationships than "friendly" to make an alliance? Help!
Please reply if you can help.
