I pposted this a few months back when i was still new here but i've thought of some ideas.Just speak up and i'll add your recource to the list:)

A list of new recources
potatoes
olives
saltpeter(you civ3er's know what i'm talking about;) )
tea
tobbaco
rubber
bamboo
copper and tin=bronze

I would add barley, salt, cotton, coffee and perhaps cocoa to that list ahead of potatoes and bamboo, together with a 'rare metal' resource to represent the key industrial metals such as zinc, lead, nickel, tin, chromium, platinum, palladium, etc...

Don't forget pepper. It was an extremely important commodity for many centuries, and one of the chief reasons for the European voyages of discovery to the East Indies. Not for nothing were the Moluccas called "the Spice Islands" by the Europeans.

Olives appear in one of the Warlords scenarios I believe.

I think tobacco could be a very interesting one. Major revenue and happiness bonuses but countered by health penalties.

Well, I had this idea, on the beermaking thread (http://forums.civfanatics.com/showthread.php?t=155944):

Hmm, I actually think that rather than "beermaking" it should be "Brewing", requiring Pottery (where are you going to ferment the beer in? A pit in the ground? Wooden barrels haven't been invented yet, remember.) In addition, I think it should be handled differently, but it leads me into an idea that's been brewing (no pun intended) in my mind for several months, so allow me to be sidetracked...

Fundamentally, I think, we should add an extra layer of resource harvesting. In addition to certain basic resources directly harvested from the land, we should add something else. The best way for me to explain is to describe it in some degree of detail.

Using the example of Beer, a good idea (in my opinion) would be to do this: for a civilization (for the sake of argument, Belgium) that has access to Grains (Wheat, Corn, or Rice), it can build up to one Brewery for every source of Grains it has access to up to five. Each Brewery provides one source of Beer, much as Hollywood provides five of Hit Movies. Thus, nations with only one source of Grains would not be able to sell their beer abroad, but those that have more could sell their wares to drier places. If we wanted to go further, we could have Monarchy be a prerequisite for building Distilleries, where a civilization with access to one source of Beer or Wine could produce Liquor, along similar rules to Breweries. Just a thought.

In any case, other resources might work similarly:

Cows: For a square with a Pasture and Cows, Workers can build Dairies in addition to the Pasture, which would increase the health benefit of the Cows and allow you to build one Cheesemaker's Shop (what else should I call it?) for every source of Dairy-harvested Cows, up to five Cheesemaker's Shops per civilization, each providing one source of (tradable) cheese. The Dairy and Cheesemaker's Shop would require Pottery and Animal Husbandry.

Textiles: A civilization with access to Textiles (either Sheep or Silk) can build one Weaver's Shop (again, what else can I call it?) for every source of Textiles, up to six (aha!) Weaver's Shops, with prerequisite Pottery. Each provides a tradable source of Cloth. In addition, with Replaceable Parts, the civilization can build up to one Textile Mill for every two Weaver's Shops, each providing an additional source of Cloth, and increasing hammers by 25%.

Leather: A civilization with access to either Sheep or Cows may build a up to one Tannery for every source of Sheep or Cows, up to five Tanneries. Each Tannery provides a source of Leather. Requires Animal Husbandry.

Don't forget guano!!! Historically important as triggers behind US imperialism, collapse of the Rapa Nui culture, the War of the Pacific and the agricultural revolution!

Waitaminute. Potatoes cause unhappiness? What planet do you come from? On the contrary, people like potatoes--they're food! The poor never dis food. Heck, they are often given examples of a Giffen good (http://en.wikipedia.org/wiki/Giffen_good).

What are the chances of seeing REAL cash crops like opium and marijiuana?

I can't think of anything that does that on a mass scale.

Actually I suspect farming for food any edible and exceptionally nutritious animal that is also either cute, furry or often kept as a pet could easily have this effect in many societies. :mischief:

It would be really cool to have saltpeter back, as requirement for all the gunpowder units (except possibly riflemen), the cannon and the frigate.

add salt, not only is it used for cooking, but it was a major preservitiave way back when. During the Roman times, salt was worth more than gold
