Whoa! Mr. President, we appear to be at war with the Byzantines. That must have happened when we booted their wandering unit? My immediate reaction is to change Rhiannon and Molly to banks and let them complete, then they can build military.
We should move all units South to combat the Byz. Leaving only a strong skeleton crew in the NW to safeguard our newly acquird cities. The Fomorch aren't going to do pop rushing, only cash rushing, so they will run out soon. Let them attack us in suicide missions. Let's see what the others say about peace with them, we may not need/want it yet.
Our strongest defensive unit is a 3. We may want to think about Nationalism next for the "no resource" riflemen. They have a defense of 6 (4/6/1).
We may want to setup all our cities to start Calvary on the same turn, trade Alex the Theory of Gravity tech for his extra Saltpeter, and commence production all at once, in case he reneges. I would also see what each tribe (that we are not at war with) will offer for our world map, starting with the Ottomans and ending with the Cairde (any order you choose) and accept. Gift the Cairde if they won't pay. Do this map trading BEFORE the Saltpeter deal.
That's all I saw at the moment, good work against the Fomorach.
