This isn't a complaint -- just something I noticed in a recent game. I was on my way to a domination victory toward the middle of the XXth Century, and Mansa Musa discovered Mass Media. It looked as though he traded it to several other civs, but (somewhat to my surprise) no one built the UN. I had to research the technology by myself and build the UN -- the AI avoided it, as if it "knew" that I had cornered enough votes to vote myself Sec-Gen and was within striking distance of getting a diplomatic win.
It was a nice touch.
