and Imperialism 2
are of two kinds:
- Wool farms or "fertile hills" (known in some countries as "sheep farms") - shown with sheep dotted over them
- Barren hills - shown plain green
Wool farms produce wool, initially one unit per turn but more when further developed by a rancher or builder.
Barren hills can be prospected and may yield minerals.
- The specific article has not been created for (or "Hill" is not part of) Imperialism
Coal and iron sources initially produce two units after the first work by a miner and two more later. For gold and gems the production is 1 then 2.
Railroads and settlements
You may build a railroad into a hill tile, and/or build a depot on it (though not in the same turn), as soon as you purchase the appropriate technology.
