Tobacco

Tobacco is the starting method for gathering gold. Each one will give you 11 gold when harvested.

Automatic Harvesting
Every tobacco that you plant will be automatically harvested on your next turn if there is still a peasant in range.

Theft
Because harvesting tobacco does not cost any action points, it is recommended to steal enemy wheat when possible. If they plant too close to you, you can harvest it before their next turn comes around.

This costs you absolutely nothing, gives you 11 gold and robs them of valuable resources (because farming is only used in emergencies late in the game).
