Ok, I note the turning by Pottery. It makes sense.
I retried the GOTM 95 but by 650 AD, I'm still far from you results :
- I'm still alive, good point, not that easy,
- I'm still willing to continue, not that easy too,
- I almost crushed the Babylonians, but I'm blocked facing the 4 last cities. It's very hard to destroy the fortified Musketmen in metros with my Swordmen.
- Every other AI have Riflemen and probably Cavalry outsite...
- And everything with the fact that I knew in advance where the Iron where and I founded quickly my second city right there...
I finally went to Monarchy before Republic and when I switched to the latest I discovered that it was a trap: I received more money from my cities, fine, 202 to 272, but with all the burden to maintain population in good mood and paying the army, my Science passed from 37 to 28 and my tax collection from 14 to 9...
Shortly, I had a efficiency (Science+Treasure)/Cities of 25% in Monarchy and it descended to 14% in Republic...
I do think I lost some time dealing with Barbs, I lost some lone warriors too easily, I was obliged to interrupt some Settler production in hurry. Next time, I will pack my warriors by two in order to be sure to crush the Barbs each time.
