Currently, I'm playing as the Kievans, since I wanted to see if it's really possible what I imagined:
Because Ukraine is surrounded by flat lands, and has enough food to easily work all tiles without farms, I wondered if it is possible to construct the perfect cottage economy. Imagine how powerful this could be: 10 or more cities, more than 200 tiles, with only towns, that can produce 2 food, 1 hammer and 7, or next to a river, 8 gold. Nobody can ever beat that science machine, and it has a decent production as well, and don't forget the specialists.
Unfortunately, it's easier said than done. There are some influential factors that prevent growth: hapiness and health limits, religious isolation, and the Mongols. Luckily, Arabia will always trade away it's resources, and Byzantium will trade you as many techs as you want. Other notes:
- The city that is supposed to flip, is usually razed by barbarians.
- Byzantium had a very high tech rate, in 1200 AD they were still tech leader. Is that new or have I been away for too long?
- There were no solid civs, 4 or 5 were unstable for quite a long time. France collapsed when I spawned because Paris was razed. Bulgaria also collapsed before 1000 AD.
- There is a hidden psychological force that prevents me to reject threats from Venezia.

- The first Mongols appeared not quite where I expected them, they spawned near my most western borders.
- Moscow has disappeared!

Is it a change in spawn date or is it something else (I'll check the WB when I come home again)
- Cordoba is winning the war against Spain, but is also unstable.
So, when the hordes are gone, I think I'm going to expand very quickly, and then build towards the cottage dream.
