being a SOB i am, I establish alliances with most of the civs with a knife held behind my back. While it lasts, I can maximize my diplomacy trading profits, and get access to higher tech weapons from trading with them, and if I'm lucky with the UP resolution, can get their econ starbases amping up my trade routes' values as well. And then I started to systematically eliminate my allies one by one, breaking the alliance just before my massive one-turn invasion step commences.
As of now, I am a few steps away from invading my 2nd unsuspecting betrayal victim, the clueless Korxes.
Then out of an instant's conscientious thought, I wonder if I will get divine retribution from other allies after they notice this pattern, or are they not programmed yet to recognize and adapt to alliance betrayals?
