So, I got to playing the save. Looks a little better than before, though still not much hope for us. This turn Innovia gave us Education. Do they expect us to give them Constitution when we finish it?
Also, A few changes I made. Most important, I think that we should use Mycenian as a GP farm. It has too much food to waste. To do that I started the National Epic there and assigned specialists. I assigned specialists in a couple of other cities as well so that they would not grow above the happiness limit. Lastly, I think we should grow New B&O quickly up to the happy cap. To this end I had the city work the tiles giving the momst food. Sorry if these changes messed up your plans for what to do with these cities.
Plans for the future: The tech plan looks good. I still think we can establish a few more cities, maybe in the southeast. We also really need to find some way to gain happyness. We can't win if we can't grow our cities over size 11 or 12.
