Sneaks is right, although you have a point about the early game (it seems the Ancient Wonders DLC skews AIs from getting key wonders?) after ~t75 tech becomes at least 50% of wonder building - in my first game since I've been back I wasn't playing very efficiently and ranked low in tech and I didn't see any WWs available in the build queue after t125 or so.
Yes, my point is only about the early game, where (somewhat like you) I've picked up 3 or 4 Wonders... after which the familiar Civ 5 snowball effect is working here as well, maybe earlier than it does anywhere else.
I have thought about the 3 new Wonders slowing down the AI - and possibly giving the human more of a crack at the Wonders the human wants - but do recall that the AI approach seemed to change with the last patch.
