A solitaire game of the Napoleonic Wars, based on the designer's Don't Tread on Me (White Dog Games). You play the monarchist Coalitions, led by Britain, and the game's A.I. plays Napoleonic France.
The game is grand-strategic; each turn covers an average of two years' real time. Your goal is to force Napoleon to abdicate, through a combination of military defeats in Europe (using your armies), and military/diplomatic defeats overseas (spending cash and diplomatic assets in a series of semi-random overseas campaigns including Ireland, Egypt, the Balkans, Senegal and the War of 1812). At the end of Turn 16 (1818-1821), if you have not defeated Napoleon, then Napoleon dies of natural causes and an exhausted Europe makes peace with his son, and you lose the game.
As a solitaire game, it is full of random events and unexpected challenges for the player, as you -- the British -- attempt to hold your unwieldy coalition together and prioritize your various budgets to win naval battles, overseas campaigns, and subsidize the various minor states of Europe whose armies are key to victory.
