I had a lovely game on starting position 7, and finally won on nation level (11.4k fame vs leader AI 11k),
as I reached the end of the tech tree at about turn 440 at slow speed.
I went: Phoenicians-Romans-Franks-Dutch-French-Swedes - kind of role player and going for science
(As Swedes, I felt obliged to go capture Scandinavia at the end...)
I covered Europe+strating area (sans Scandinavia), had a peaceful game.
At the end at ca. turn 435 I started a war against Beowulf who was an era behind me, and had a quick conquest of him,
which would have been ended with killing him off, had I not ended the tech tree so suddenly (I had one tech left but that was not an end-tech)
2 AI civs were killed - I think starting position 2 (Guiyang) and 3 (Arjuna)
