Goody Huts don't work as manual states

[Kolyana]

I've had settlers AND a city ... it's rare, but I've had it.

The calculations and figures can be found in the editor, I'm sure ::innocent expression::

I have played probably 200 hours in play time and have seen only two settlers and no free cities. Expansionist civs definitely give better results but the benefit does not outweigh the lost attributes of the other traits. I don't play the expansionist civs anymore because I can always get the advances by trading or beating up my neighbours.

I've gotten nomads, both as expansionist and not. Very rare, though in one expansionist game, I did get two.

For all of you that think expansionist is useless, I predict that MP will be the great revival for expansionists. Getting a handful of early techs while your opponents are getting barbs and empty villages will be a BIG BIG advantage. Especially if the trend of one night MP games continues. There won't be enough time for the other traits to make up the difference of 8 or 9 good huts.
