Just thought this would be helpful to you for resource distribution. While working on the many crop buildings i would frequent wikipeda and learn some new stuff about them, specifically where crops originated. Here is a list of resources and where they were originally from.
Almond = Middle East and Indus Valley
Apple = Turkey (Asia Minor)
Banana = Southeast Asia, Eastern India, Southern China (
See Map)
Barley = Fertile Crescent
Coffee = Ethiopia
Corn = Southeast Mexico
Cotton = Indus Valley
Dye (Indigo) = ?
Fig = Middle East
Flax = Eastern Mediterranean to India
Hemp = Central Asia and South Asia
Incense (Frankincense) = Arabian Peninsula and in North Africa
Lemons = Southern India, northern Burma and China
Mango = Northern India, Burma, and Western Malaysia
Melon (Watermelon) = Southern Africa
Olives = Mediterranean Basin, western Asia and northern Africa
Opium = Middle East
Papaya = Southern Mexico, Central America and Northern South America
Papyrus = Egypt
Potatoes = Southern Peru
Pumpkin = North America
Rice = Yangtze River valley in China
Rubber = South America
Spices (Cinnamon)= China? Egypt?
Squash = North America (yeah all of them)
Sugar = India and Southeast Asia.
Tea = Asia and Southeast Asia
Tobacco = North America
Wheat = Middle East
Wine = Georgia, Iran and Armenia
Not sure if this helps for map making, but it thought it was interesting.
