I've had a chance to play this a few times, and its a great merge; the only graphical issues that I've noticed is that a few civs seem to have their flags and colours distorted (for some reason, they are sideways and photonegative; so for example, Canada, whose flag is red and white and whose colour is red, for some reason now has a pale green and black, sideways flag with pale green as its colour). I'm not sure whether this is a problem with your mod, or whether it is just a problem with the latest version of CivGold
