2nd attempt.
Emperor/Epic. Also, I turned off Events & Vassals as well as Espionage since in an OCC it is not at all fair.
This try I went with cottages on the flood plains instead of the farms since, as you can see, early health is non existent.
Ran Parthenon - Great Library - National Epic - Pacifism for most of the game.
Stayed away from Globe Theater and went Ironworks & Heroic Epic.
Used Market, Cathedrals, Temples, Incense & 2 Eiffel Tower enhanced "Hits" for the extra happiness up until the war.
Somewhere between 1600AD & 1800AD I swapped cottages for State Farm powered watermills and workshops.
Used the Chariot & Samurai hammer overflow to gold trick to raise my gold reserves sometime starting in the 1300's. Of course there are numerous wonders and improvements that interrupted the queue during the 1300-1700's so I did not get as many units or gold as I would have wished.
Here are some screen shots.
Missed Oracle all together. Did not pop a single tech from a hut.
1 turn from Liberalism in 900 AD. Had a Great Engineer saved for a quick National Park.
1030AD
1370AD. My Hammers were in pretty good shape at this point considering I didn't have a Factory or Shale Plat (which provides power regardless of coal).
1515AD. Swapped from all Scientists to Angkor Wat Priests a little while earlier. Added another 100 hammers per turn total.
1610AD. Made final swap to all Engineers & Priests and railroads on mines. Only 8600 gold at this point. I will need alot more to upgrade those samurai.
1812AD. Didn't have a save of my pre-war empire but here are some shots just after the start or war. 4 Great General Mech's lead the charge with CRII, Drill IV Mech's on cleanup.
1836AD. Infantry are showing up in force. Surprisingly they are not a problem. Machine Gunners are worse with the +50% Gunpowder and the canceled First Strikes. Have started to take heavy losses so I have slowed down substantially. Hopefully I can pillage improvements while waiting 3 turns for a single reinforcement, even having railroaded in enemy territory.
