I'm actually going to cast my vote for the builder route. Since we have copper, Hatty doesn't pose a threat to us. If she's the only AI on the continent with us, then she won't trade with us, but she can build and develop cities for us to conquer later. A not-axe-rush early game might be a fun change of pace too. With Imhotep's scoring system, we'll do better as builders anyway, and when we do harvest the Egyptian empire, there will be more unit-kill points for us too.
