With 3 of the 4 closest city states being cultural, clearing barb camps and returning workers netted me 2 cultural CS allies leading to finishing Liberty on T58 - got a GE, but wasn't ready to use it yet.
Philosophy on T60 and 4-city National College on T62, immediately building a 5th city (I had less than 400 gold, so that settler was just waiting) and science was at 41.
T69 finished Pyramids and have 8(!) workers; I deleted several in early T100s as there wasn't much left to do
Opened Patronage T72, finished the Oracle T81, and got Scholasticism on T89 - had 2 CS allies at the time and 1 friend. At T89 science was at 71: 54 from my 5 cities, 10 from TR sent to me (I wasn't sending any out), and 7.5 from CS
T103 Education. Built all universities (by T119 I think), saving gold as I tech to Navigation
Opened Exploration (+1 movement and sight to naval); I think this was decently helpful, probably my first time opening the policy tree
Got Navigation T125 but didn't have much gold yet. DOW'd Persia a few turns later, partly to start getting XP on existing units
T146 captured Persepolis (1)
T150 Science is at 301 (Persepolis still in resistance) and we have Tech lead by 2!
T153 Chicago, which was East of Washington and my 'base' from which to attack the capital
T162 captured Washington (2): 10 wonders, including Great Wall, Forbidden Palace, Notre Dame, and Himeji Castle!
*shortly after getting Washington I split the army in 2. Land units finished of America then started on Rome, with new land units bought/purchased in Washington. Iroquois DOW'd me after T177, when I wiped out America, as I was still putting together a 2nd army for them and India, which was a combo of land and naval units.
T165 Oxford-Dynamite
T192 Onondaga (3)
T194 Rome (4), had Zeus
T200 Ideology: Autocracy. I don't remember going Autocracy before. I had 2 GW and 2 GA saved up to help get policies, but at this point it really didn't matter
T207 Addis Ababa (5)
T216 final 2 Athens and Delhi, same turn
Artillery with a good road network are fantastic! As are logistics Frigates!
