Very enjoyable game. I look forward to more GOTMs with settler-less starts, it's a change from routine.
In 475bc after taking Persepolis, Kyoto and Akkad (hindu holy city), had 4 rivals: Babylon, Zulu, Pacal and Pericles. I was at a crossroads: should I attempt conquest or not...
I decided to go for culture, reasons:
(1) I'm lame on conquest/domination (Roman GOTM confirmed this)
(2) Wanted to have a go on the Philosophical trait
and especially (3)Persepolis was in a sweet spot for wonders and GP farming, what a dream
4 cows, flood plains, hills with iron, it looked beautiful.
Decided to make Kyoto a military and support city, wanted FP tiles for the 3 legendary.
The AI researched slowly and built even slower, so I had the pick on the wonders... built all those that matter and also the ones to enhance GPs.
Pacal expanded but never became dangerous, Hammy wasn't a serious cultural competitor, was busy expanding and also got crippled cos I pillaged his capital's cows during taking of his holy city.
Pericles was barely expanding, more concerned about convert other civs. He tried to convert zulus to his judaism, but I was faster and converted them to confi. Later he would convert Hammy though. Pacal was buddist.
I had heaps of fun, the game was largely micromanagement, and I would give old techs whenever they asked. Nobody ever declared war on me (kept military in check, unlike BOTM58), Pericles even asked to be vassalised
Had 1 turn of anarchy for slavery and that was it
(edit: My mistake. There was also confu and OR changes anarchy). In 1400ad, triggered a GA (was forced to spend a Great Artist, needed to revolt asap) and changed to Pacifism, Caste, FS and Rep. 2nd GA came with Taj (switched to Mercantilism), 3rd GA with GP and GS. 2 turns after this GA ended, had 4th GA with GS, GP and Economics GM. Total 48 turns in Golden Age.
The Philo trait helped heaps, Persepolis was producing 450% GPP during GAs. 350%GPP on the other big 2 (Moscow + St Petersburg). Built 15 cathedrals, and thanks to wonder and representation powered specialists managed to keep culture slider at 100%from start to end of GAs, still researching.
Culture victory 1735ad. I don't think I would be able to do it in a much higher difficulty game though, the AI let me have the pick on wonders, stayed peaceful, it was really a builders game... glad I took Persepolis instead of going east...
And to think I almost ruined my game at the start by inviting mongols to attack in forest and hills... I forgot mounted don't get defensive bonus
