Carcassonne - Expansion 2 - Traders and Builders

The second major expansion to the original game of Carcassonne Traders & Builders contains 24 tiles with new features such as Bridges and Cities.
Some tiles also feature symbols for the goods Wine Cloth and Wheat. Players collect one of these goods when the feature that has it on the tile is scored. Players with the most of each type of good gets bonus points at the end of the game. There is a popular house rule that allows the trading of goods between players in exchange for other goods and the ability to chose where a tile is placed. There are also two new wooden playing pieces in this expansion. The Builder is like a meeple in that it may be placed in a city or road as a kind of supervisor. A subsequent tile extension of the feature the Builder is in allows the player another tile placement. Farmers will also be able to place a new Pig pawn in a field for extra points at the end of the game.
Finally Traders & Builders comes with a large cloth bag. Not only does this make it easier to keep and handle the tiles but it also removes the problem of having non-identical backsides.
Carcassonne: Traders & Builders Expansion Play Summary

Traders - Some of the new city tiles depict goods: wine grain and/or cloth. When you complete a city your own or someone else's you collect a matching token for each good in the city. At game end whoever has the most goods in each category scores an additional 10 points.
Builders - Each player receives a builder meeple in his color. You can add your builder to any city or road you already have in progress.
