I understand that Sailing opens foreign trade (usually meaning 2G instead of 1G for coastal early on).
So Sailing is somewhat interesting tech for trade (and also is required for Calendar/Compass).
Looks like I miss the point with exploration of foreign cities to enable foreign trade roots:
* is it import to explore the coastal line to foreign city?
* to every foreign city or to as many as my cities?
* is it symmetrical for both sides or only for those who invested in exploring?
* what is a typical unit used for exploration: Work Boat or Warrior?
* can I trade 1 foreign to N mine or it is 1-to-1 and I need keep exploring more foreign cities?
The problem arises because I tend to fogbust so I usually reluctant to move Warriors out of place or build one extra. Probably that is a mistake and I have to improve on that.
