Thank you. Everyone should really remember that the reason I'm lagging in REX is because we went a-wonder-whoring, and that path was the general consensus amongst the peanut gallery here.Generally speaking, 4 cities in 300BC is weak, but sometimes your surrounding lands just cannot produce enough commerce to support anymore than that. What that means is that he's stuck at 4 cities because of commerce. If that is indeed the case, then while a dedicated military effort would surely work against any emperor AI, eliminating a rival and getting more cities won't solve your original problem. If his lands are commerce-rich, on the other hand, then yes, it is sloppy gameplay, but after over 20 ALC games, I doubt that his play could be classified as "sloppy".

Well, the wonder-whoring is over for now, so it's time to turn our attention to making that "slingshot effect" happen. Fortunately, the barbarians have founded two well-located cities for me, so that saves me two Settlers--and they're holding on to that land, as it usually takes the AI quite some time to build up a force to take barb cities, and I can slow that possibility down further by closing my borders, in particular so Zara can't waltz over there and set up shop in my backyard (which you just know he's dying to do). Thus, building up some military will both help my power rating and my lack of cities. As I mentioned, I'm also hoping to capture those two barb Workers to help out in that regard.
Nevertheless, as we mentioned, two additional cities need to be founded ASAP--the SE blocking city and the tundra iron city--and many more Workers are needed. So I'm going to have my hands full in the next round. I think the two cities and more Workers are the top priorities. I'll need to at least have that copper hooked up and generate more units--and possibly research HBR--before I'm even close to go capturing cities, so those 2 cities will likely remain barbified until late in the round at the earliest.
After Validator's perceptive (as usual) post, I am leaning back towards infiltration with the GSpy, though generating regular Spies is going to be tough what with the lengthy to-do list I have.
