Ah, for some reason I thought BtS got rid of or at least reduced those weights. The Power rating would be bad though, as the AI uses this to make military calculations, at least it would be bad to give it unrealistic power. I forgot how Asset fits into AI logic, you remember? Will be nice if this works though, I was looking over CvCityAI.cpp and without a known call for the SDK to recognize the modified upgrade cost, I wasn't really sure where to start.
And the AI will build any wonder, no matter what it does if it's flagged with a wonder tag, but that's just a chance of hitting the lottery. At least form what I see the AI is not prioritizing LW.
Thanks for the quick response, any word you can give me on the progressive trait, or should I look into working on this myself? I'm not a master of trait effects like yourself, but I could give it a go if you're no longer interested.
