My first ever Monarch win of any kind, on my first try at this Gauntlet!
Squee! (Well, I did have barbarians off, and hand-picked neighbors.)
1861.
Continents map, Gandhi-Warlords. Two big continents -- I found Buddhism and spread it to everyone on my continent, forming the giant Buddhist block that usually destroys me in non-cultural mid-games. Kept up in tech using ridiculous tech trading all the way up to Constitution when I realized I didn't really need any more tech. My only wonders: Pyramids (400 BC) and Great Library (545AD

). I got a lot of yucky great people that I didn't want.
In the end, founded four religions (Buddhism, Christianity, Taoism, Islam) and built 8 cathedrals. 9 great artists got dropped into various cities. For all the cottages I ran, I really should have been financial, not philoisophical!

And finally, another first: with barbarians off,
no one on my peaceful Buddhist continent ever saw a single battle!
Flipping of national wonders
I did culture-flip a city with Ironworks, which was fun since I didn't get the prerequisite tech until the very end when Cyrus gave it to me. Ironically, it also had Hagia Sophia!
