Cossacks is also the name given to a computer game by GSC released in April 2001. The German game borrows a lot from Age of Empires but also improves upon it. It is based in 17th and 18th century Europe. The game features a massive unit limit of 8,000 men, a large variety of nations to play and a very interesting array of tactics which involve strict coordination of your cavalry, artillery, infantry and navy. The game also requires the player to build a vast economy to support his armies and navies. For further informaion I recommend the Gamespy review: http://www.gamespy.com/reviews/april01/cossacks/
