If you search at all on these forums for runaway ai's you will find plenty pre new wonders.
The runaway ai is in no way shape or form strictly from the new wonders.
If a super expansionist like mongols or greece, there are a few others I forget, are on a continet with someone like ghandi then they will get crushed and the ai will super ics the whole continet without constrait of happiness due to the "we wont fix the problem of bad ai just cheat them with extra everything". That is why they ran away and out teched gold everything you, not from 10 happiness and 1 extra health per turn.
This entire thread is about the wonders being op for the human player, not the computer as they cant utilize the new wonders properly.
Tho I still believe that the new wonders to not give even a human player a IWIN button anymore than the bad ai design has in the pre patch era.
Keep on topic, keep on topic!
Bad AI is one thing, OP Fantasy Wonders are another!
Ok, I am here to reconsider and say that New Wonder aren't OP. They are simply broken - when I click, lets say, "Immortal" difficulity level I want to actualy PLAY Immortal game! But, wooo! I began my game and found El Dorado / Fountain of Sillyness next to me - DIFF level just dropped one level instantly. Restart! RESTART!
But my very first point stay valid - if anyone do not like the new wonders, disable/nefr them manualy. We have the technology xD
