I played my turn. I mostly continued building units and exploring. I switched to Macemen and Cats since we already had quite a few Knights. Exploration shows all the perimeter of HC's island and most of Sladin and Roosevelt's. There is still a lot of work to do. HC upgraded to Longbowmen in 1112.
At some point I sunk one of his Galley with one of our Caravel. Before that I had seen 2 of his Caravels go around our island, one south and one north.
Our upkeep continues to go up since we are getting more units. In order to keep research at 70% I decided to trade Literature to Saladin for 80 gold. Not too good but I thought it was worth it. We are 4 turns away from Asrtonomy.
I did not switch to Theocracy as it would have been even more expensive. I also did not switch to Caste system as I wanted to grow Elephantine. But we could do it now.
Current situation:
Thebes: 1 Scientist, 1 Maceman
Memphis: 5 Knights, 1 Maceman, 2 Cats (plus 1 on its way)
Elephantine: 3 Chariots, 2 Maceman 1 Cat (plus one on its way)
Alexandria: 1 Warrior, 1 Knight, 1 Maceman
Moscow: 1 Chariot, 1 Maceman
Novgorod: 1 Chariot, 1 Knight
Pi-Ramesses: 2 Chariots, 1 Longbowman, 1 Maceman, 1 Knight
Heliopolis: 1 Warrior
