While other game options are available, like playing campaigns focusing on Britain or Prussia (just like the main campaign in Empire: Total War vs the other single player options), it is no secret that the game revolves around him and the wars he started - after all, his name is on the box.
Even the tutorial focuses on Napoleon as a boy, where you lead him through his first steps towards power. The main part of the game, the Napoleon Campaigns, have you controlling him and his armies as he builds his empire from being a minor general fighting against Austria, through Egypt and Europe and finally up to Waterloo. In some ways, it feels odd to focus a whole game around one man. Now Creative Assembly is back and while the background is pretty much the same as in Empire: Total War, they have now decided to focus on one the most interesting character in the 18th and early 19th centuries - Napoleon Bonaparte, also known as Napoleon I. It's of course a matter of taste, but quite a few commenters let me know how wrong I was. When I reviewed Empire: Total War once upon a time, I mentioned that the time frame that game was set in felt pretty boring to me.
