Whether you find yourself drawn into the rivalries of Italian city-states on your march to Vienna, or watch as your corps wither away in the harsh Russian winter, Napoleon is fairly faithful to the historical situation. It certainly allows the team the chance to let players take on some of the specific challenges and situations faced by Napoleon himself. You have to take the scripted nature of the campaign for granted, if only for the sake of the story telling. In telling the story of Napoleon, Creative Assembly created a narrower, more tightly scripted series of three campaigns, four if you count the tutorial. And since Alexander and Caesar already have their own Total War games, it only made sense that Napoleon would be next. The spectacle of war was at a particularly high point and Napoleon dominated the era with a forceful personality and ambitions that rivaled those of history's other great conquerors.
He lived during a time of revolutionary technological advancement during which a number of powerful nations were in direct conflict with each other. In many ways, Napoleon Bonaparte is the perfect subject for a Total War game.
