More Mercantile Mod
This mod adds new Luxury Resources for Mercantile City States into the game. The changes are purely for flavor and they have little effect on the games themselves. The Gods and Kings expansion pack is required to use this mod (Both for Mercantile City States, and for the icon used for Manuscripts).
The resources added are:
Chocolate
Manuscripts
Tea
Glass
Furniture
Cigars

Spoiler :
Chocolate is a raw or processed food produced from the seed of the tropical Theobroma cacao tree. Cacao has been cultivated for at least three millennia in Mexico, Central and South America. Its earliest documented use is around 1100 BC. The majority of the Mesoamerican people made chocolate beverages, including the Aztecs, who made it into a beverage known as xocolatl, a Nahuatl word meaning "bitter water". The Europeans sweetened and fattened it by adding refined sugar and milk, two ingredients unknown to the Mexicans. By contrast, the Europeans never infused it into their general diet, but have compartmentalized its use to sweets and desserts. In the 19th century, Briton John Cadbury developed an emulsification process to make solid chocolate, creating the modern chocolate bar. Although cocoa is originally from the Americas, today Western Africa produces almost two-thirds of the world's cocoa.
Manuscripts

Spoiler :
A Manuscript or Handwrit is written information that has been manually created by one or more people, such as a hand-written letter, as opposed to being printed or reproduced some other way. The term may also be used for information that is hand-recorded in other ways than writing, for example inscriptions that are chiselled upon a hard material or scratched (the original meaning of graffiti) as with a knife point in plaster or with a stylus on a waxed tablet (the way Romans made notes), or are in cuneiform writing, impressed with a pointed stylus in a flat tablet of unbaked clay.
Tea

Spoiler :
Tea is an aromatic beverage commonly prepared by pouring boiling hot water over cured leaves of the Camellia sinensis plant. The term also refers to the plant itself. After water, tea is the most widely consumed beverage in the world. It has a cooling, slightly bitter, astringent flavour which many people enjoy.
Glass

Spoiler :
Glass is a solid material that is typically transparent and brittle and has been used for centuries in windows and drinking vessels. The history of creating glass can be traced back to 3500 BCE in Mesopotamia. The term glass developed in the late Roman Empire. It was in the Roman glassmaking center at Trier, now in modern Germany, that the late-Latin term glesum originated, probably from a Germanic word for a transparent, lustrous substance. The center for luxury glassmaking from the 14th century was the island of Murano, which developed many new techniques and became the center of a lucrative export trade in dinnerware, mirrors, and other items. What made Venetian Murano glass significantly different was that the local quartz pebbles were almost pure silica, and were ground into a fine clear sand that was combined with soda ash obtained from the Levant, for which the Venetians held the sole monopoly.
Furniture

Spoiler :
Furniture is an object that is intended to support various human activities such as seating and sleeping. Furniture is also used to hold objects at a convenient height for work (as horizontal surfaces above the ground), or to store things. Furniture can be a product of design and is considered a form of decorative art. In addition to furniture's functional role, it can serve a symbolic or religious purpose. Furniture can be made from many materials, including metal, plastic, and wood. Furniture can be made using a variety of woodworking joints which often reflect the local culture.
Cigars

Spoiler :
Cigars are tightly-rolled bundles of dried and fermented tobacco that are ignited so that their smoke may be drawn into the mouth. Cigar tobacco is grown in significant quantities in Brazil, Cameroon, Cuba, the Dominican Republic, Honduras, Indonesia, Mexico, Nicaragua, the Philippines, and the Eastern United States. The word "cigar" originated from the word "cigarro" in Spanish, which probably came from the Mayan "sikar" ("to smoke rolled tobacco leaves" – from sik, "tobacco;") or from the Spanish word cigarra ("grasshopper"). However, the word itself, and variations on it, did not come into general use until 1730. New names for cigars include "Jules", "Havana", "Vitole" and "Puro". An older alternate spelling is "segar", not uncommon in 19th century signs and advertisements.
