Wow! There is really a lot of food here. Looks like you can have 25-30 cities before 1000BC! Or whip a decent army and go rampaging around about the same time. If you can grab everything: cows, game, wheat, flood plains ... You can be fine probably even without settler factory. Just build settlers and workers in all these cities. And capital can be used for barracks and warriors. Wow! Indeed, lots of food.
