Well first thought is we are in a pretty dire situation
I suggest putting a city that caaptures the two gold north of Mycrean this will help money wise. Tech wise banking is certainly the right option at the moment, I suggest that we go for education to gain acces to universites which will help our science which is behind the pace. Also miltary needs to be improved from one unit guarding the city to a miltary able to counter-attack a real attack although against barbians that shouldn't be a problem. Our production are good so if war comes we do have the capablities to build some units before an attack. I don't know though, this being my first time i don't know whether there is a real chance of one of the other teams invading but I sure wouldn't like to be caught of guard.
