Frank Hunter's Campaigns on the Danube is an operational study of the campaigns along the Danube in 1805 and 1809. Campaigns on the Danube's system focuses on trying to present the player with the same sort of decisions placed on their historical counterparts; how to feed an army and move that army according to a plan, all the while trying to fight a campaign. There is also an option to allow players to play out the battles with miniatures and input the results.
