Today I have beaten my personal record winning at turn 222 with Holland. Of course I did it with a very lucky start, but with a normal start you can expect 250 wins.
This is my personal Hall of Fame playing only OCC Deity Science:
(It is in spanish but I guess the data shown is clear).
Pangea, Standard speed and map size, Deity and I guess you can see it's OCC only due to the low score.
In the most shocking ones like Holland 222 and Maya 226 I had Petra (It is game breaking). In all of them I had an observatory in place except for 265 Babylon.
I try hard to have an observatory it is too important (affects research speed, RA output and burned GS output.
I have the initial save of my Holland 222 win. I have attached the file.
DLCs present: all civs except Polynesia and Denmark and Ancient Wonders.
I hope there is not a problem with the file for having the game in spanish.
I moved the settler twice and founded on the cotton (There is only 1 polder place so you play without UA at all, but you have mountain, river, nice desert tiles for Petra and abundant luxuries, quite an astonishing starting place, so I guess anyone could beat my record).
You are cornered in the map, surrounded by some CS and only Austria is near (really close In fact and will attack you many times and finally marriage all those CS completely surrounding you xD). You have aluminium (although I always buy it from the AIs so I sell it for cash) oil (although due to my techpath I always discover it while building the spaceship so no use at all) and 4 horses outside your City Radius.
About doing a let' play I don't feel like talking alone while playing but I guess I could do a kind of let's play with screenshots.
I have uptated the Opening post with many new info, I think I didn't really explain the last part of the game which is a bit tricky.
For me, the main thing to speed up your wins are the use of Spys to get friends, a planned techpath, avoid getting unwanted GPs, a Mountain and money to pay your RAs on time.
