Hmmm, it really depends on the game indeed.
If silk is near a river bed, and on a forest (which is often the case), planting a cottage down there makes it a hell of a resource field.
Before I have calendar the cottage will have grown to big heights, so the income will certainly be higher then a plantation on it.
If AI's are hungry for silk, I will plantation it, if I feel the need is there to trade it.
Factors/factors/factors. Aint civ a great game?
