Speaking of friendships and friendliness "locking" -- I am currently in a Deity game on turn 86. I have met 4 of the other 12 civs (besides myself). All 4 are currently friendly with me. I don't even send a delegation the turn I meet them (this is an exploit in the game coding imho) -- I have a rule that says I can only send those after receiving one. Well, received one in 3 out of 4. This is Deity. Not a single war. Will there ever be one? Knowing prior experience, my answer is no. How freaking boring, still today. I'm going to play a little Civ 3 again and see if the AI actually has brains. EDIT: I did have one that denounced, but after that expired, yep, friendly.
