I just looked at the 1000 BC and 10 AD saves of @ignas 440 AD Tiny 100k (30k) game. They are hard to believe! 24 cities with 8 settlers built and 24 workers at 1000 BC....and researching Invention! At 10 AD, ignas already had rails going and had Replaceable Parts!!! He was back-filling Music Theory for JS Bach's and the happiness it provides.The Internet completed in 810 AD. Here's another screenshot.
We had 38,629 culture at 1159 culture per turn in 800 AD.
And 40,156 culture at 1527 culture per turn in 810 AD.
59 more turns would make for a finish of 1325 AD, I think.
If history is a guide, this should be a 1240-1250 win date, if you are able to maintain culture adds at a good pace. I note that with 35 turns left to go on straight math, I was able to improve 4 turns from there. But I had blown through my culture adds at that point and had I had a stronger pace, I might have pushed ahead 1-2 turns.Projected finish date has kept on dropping a turn or so the last few turns.
At 920 AD we have 59946 culture and 2008 culture per turn.
This projects victory in 35 turns, which would be 1260 AD or 1265 AD.
