I am impressed with this game. I am agricultural, spamming out cities like nuts, and am not even in the top two in score.
Did Banzai pop a few settlers? Get a 4 cow start?
That being said, I am now in my Golden age.
I love Emporer A.I.'s Always attack when I am not ready, but can never bring the thunder enough to really do you in.
Expect more trouble.
