I finally got around to submitting my game.
I manually built:
Forbidden Palace-470 B.C.
Sun Tzu's - 10 A.D.
Magellan's-420 A.D.
Leo's-650 A.D.
(Yes, you CAN build wonders using an extreme ICS). You just need to pre-build for them. I got Magellan's completed 3 turns after getting navigation.
I had probably about 8 or so caravels ready to explore when I got navigation and they were spread out nicely to explore in all directions, so contacts were made quickly.
Navigation:390 A.D.
410-Met Persia and got contact with England
420-Met Greece and got contact with Rome
430-Met Russia and got contact with Germany, America.
480-Met Babylon and got contact with Zulu, Iroquois
540-Met Aztecs and China (both at the same time, my caravel landed right where their borders met).
Conquest:
270 AD-Egypt dead (swordsmen and a couple numidians)
810-England dead, Persia dead (knights)
1110-Greece dead (cavalry for them and all the rest of the civs)
1120-Aztecs dead
1130-Rome dead
1160-China dead, America dead (by Germany)
1170-Russia dead
1190-Germany dead
1210-Babylon dead
1265-Zulu dead
1275-Iroquios dead.
The turn after I got military tradition, I had 30 cavalry (and 30+ more horsemen waiting to upgrade, but I had to wait for cash to build up) and sent 3 caravels towards Aztecs/China (that is all I need for them, and all but 1 or 2 cavalry survived), the rest I sent at Rome, then I started sending some towards other civs before Rome/Greece was completely taken care of.
I didn't get any leaders until very late (built armies as I had no other use for them, except the last leader I rushed the heroic epic, but the game was over like less than 5 turns later). In fact I even disbanded one leader because I forgot not to raze the last China city, so I couldn't do nothing with the leader except spend 15+ turns shipping it back home! (that's 15 turns of not getting a chance of getting another leader in a more suitable location). I built an army late in the German war and loaded it up with knights, only to realize I can't ship a fully loaded army (3 units, plus the leader) into a caravel
I sold fuedalism to Rome and Greece for all thier money shortly before invading them. The reasoning was 1.) Sun Tzu's was already built and 2.) They would hopefully build the more expensive pikeman instead of their cheap UU. (all had defense of 3, so I would rather they build the pikeman).
