In Great Western Trail: Argentina, you own a vast estancia in Argentina at the end of the 19th century, and you will need to travel the plains of the Pampas with your cattle to deliver them to the main train station in Buenos Aries.

Great Western Trail: Argentina features gameplay elements similar to Great Western Trail such as deck management, the rondel mechanism, and the ability to upgrade your player board, along with twists on these elements and new features.

The player board features a new type of worker — farmers — and different paths await on the game board to confront you with more choices. Will you take the road with buildings or a path past farmers? Maybe you'll have the chance to use your cows — well, the strength on your cow cards — to help farmers, getting them on your side and adding grain, a new type of resource, to your income, with grain being used for boat and city tiles.

Great Western Trail: Argentina also includes a solitaire challenge in which Pedro is waiting for you to try to beat his score.
